Illinois, Illinois

In March 2026, construction crews lifted the first structural steel beam at the old U.S. Steel South Works site on Chicago's Southeast Side — ground that once forged the metal that built the city, then sat vacant for decades after the mill closed. The roughly 500 tons of steel going up there now will hold a building for PsiQuantum, the anchor tenant of the Illinois Quantum and Microelectronics Park, a 128-acre campus where the state has committed $500 million toward what its backers describe as a roughly $9 billion redevelopment, and where the company intends to build America's first utility-scale, fault-tolerant quantum computer. The same spring, three other Illinois stories ran on parallel tracks: a federal appeals court upheld the corruption conviction of the longest-serving legislative leader in American history, the Chicago Bears' board voted to advance a stadium plan in Indiana, and the governor who faced down a federal troop deployment cruised toward a third term while bankrolling his lieutenant governor's Senate campaign. That is Illinois in one season — a state rebuilding on its own industrial bones while arguing about who gets to leave, who goes to prison, and who stands between it and Washington. For most of American history, Illinois picked presidents. Now it defines itself by what it resists.

The Lay of the Land

Illinois is a wedge of prairie driven between the Great Lakes and the Mississippi River, 57,914 square miles that rank just 25th in area while holding the nation's sixth-largest population and fifth-largest state economy. The shape itself was a political decision: when statehood came on December 3, 1818, the territory's advocates had pushed the northern boundary up to capture Fort Dearborn and a sliver of Lake Michigan shoreline, connecting the new state to the Great Lakes and, eventually, the Atlantic trade. Everything about modern Illinois flows from that sliver. Chicago grew at the northeast corner where the lake meets the prairie; the Illinois Waterway ties the lake to the Mississippi and the Gulf; the Ohio and Wabash rivers frame the state's southern reach.

The political map reads in three layers that function almost as separate states. Cook County holds Chicago and its inner suburbs — the largest county, casting more than two million presidential votes. Around it sit the five "collar counties": DuPage, Lake, Kane, Will, and McHenry. Everything else — 96 of the 102 counties, from the Wisconsin line to Cairo at the confluence of the Mississippi and Ohio — is "downstate," a term locals apply as a political direction rather than a compass one, since it includes Rockford-area counties that sit north of much of Chicagoland. Between the metros runs the grid: the corn and soybean ground that makes Illinois the nation's top soybean producer, the county seats strung along the rail lines, and the interstates that make the state a continental crossing point.

How It Got Here

The French explorers Jacques Marquette and Louis Jolliet came through in 1673, and the state's name is a French rendering of Illiniwek, the name the region's Algonquian people used for themselves. The deeper past sits at Cahokia Mounds near the Mississippi, the remains of a pre-Columbian city. But the identity Illinois sells the world dates to one Springfield lawyer: Abraham Lincoln, who built his political career in the state and whose presence still anchors the capital — the presidential library, the preserved home, the official "Land of Lincoln" slogan. More than 250,000 Illinois troops fought for the Union. After the Great Chicago Fire of 1871 leveled the city, the rebuilding produced the world's first skyscrapers, and Chicago spent the next century as the industrial capital of the interior — steel at South Works among its engines.

The counter-history sits in Lincoln's own hometown. In August 1908, a white mob attacked Springfield's Black community, lynching two men — Scott Burton, who defended his home with a shotgun, and William Donegan, an 84-year-old cobbler married to a white woman — killing at least six others by gunfire and driving roughly 2,000 Black residents from the city. Towns across central Illinois turned away Black residents in the riot's wake. The shock of racial terror in the Emancipator's city catalyzed the founding of the NAACP the following year. The site stayed mostly buried until archaeological work tied to a Springfield rail project documented the foundations of burned homes, and in August 2024 President Biden designated the Springfield 1908 Race Riot National Monument — six weeks, as NPR noted, after a sheriff's deputy shot and killed Sonya Massey, a 36-year-old Black Springfield resident, in her own kitchen.

The other inheritance is governance as recurring crime scene. Four Illinois governors since the 1960s went to prison: Otto Kerner (convicted in 1973 on bribery and related charges tied to horse racing), Dan Walker (1987 guilty plea, bank fraud after leaving office), George Ryan (convicted 2006 in the licenses-for-bribes scandal that began with a fatal highway crash; he died in 2025 at 91), and Rod Blagojevich (impeached in January 2009, convicted in 2011 of crimes including trying to sell Barack Obama's vacated Senate seat, his 14-year sentence commuted by President Trump in February 2020). A 2023 University of Illinois Chicago study ranked Chicago the most corrupt city in America for the fourth straight year and Illinois the third-most corrupt state. The tradition is not historical. Michael Madigan — 50 years in the General Assembly, 36 as House Speaker, the longest tenure of any legislative leader in U.S. history — was convicted in February 2025 of bribery conspiracy and wire fraud centered on a scheme the Seventh Circuit later described as exchanging political influence for more than $3 million in benefits to allies, much of it involving the utility ComEd. He was sentenced in June 2025 to seven and a half years and a $2.5 million fine, reported that October to a minimum-security camp in Morgantown, West Virginia, and on April 27, 2026, the appeals court upheld the conviction, writing that this "was not politics as usual." His lawyers have signaled a possible Supreme Court bid. The arc lands squarely on the present's doorstep.

Who Lives Here Now

About 12.72 million people lived in Illinois as of July 2025, by the Census Bureau's latest estimates — and the number itself has been a political fight. The 2020 census recorded the state's first decennial population decline since statehood, a loss of roughly 18,000 over the decade, and annual estimates through the early 2020s showed year after year of shrinkage, with Cook County posting some of the steepest county-level losses in the country between 2020 and 2023. Then the story turned twice. A state-requested federal review found about 46,400 residents missed in group quarters in the 2020 count. And the estimates themselves reversed: Illinois has now added population for three consecutive years, including 16,108 residents between mid-2024 and mid-2025 — more than 100,000 since 2022, a run the Pritzker administration promotes heavily, though the state remains roughly 100,000 people below its 2020 level.

The growth is narrow. Only 15 of the 102 counties gained residents between 2020 and 2024, among them outer-metro Kendall, Grundy, McHenry, and Will, plus university-anchored Champaign. And the age structure is moving fast: Governing reported in 2025 that Illinois has lost more than 172,000 residents under 18 since 2020 — a 6 percent drop, the fastest rate of under-18 decline of any state — while the 65-and-over population grew by 62,500 in a single year. One analysis benchmarked to 2020 census data projects the state could slip from sixth to eighth most populous by 2040. The state that is finally growing again is simultaneously growing old.

The Work

The economy is the country's fifth largest and unusually diversified for the Midwest — finance and exchanges in Chicago, logistics across the interstate grid, and a farm sector that leads the nation outright. Illinois is the number-one soybean state, producing 688 million bushels in 2024 by USDA's count, and second in corn at 2.31 billion bushels. It is also, less famously, the number-one pumpkin state: 485 million pounds in 2024, most bound for the cannery in Morton, the self-styled Pumpkin Capital of the World, which by local accounting fills roughly eight of every ten cans of pumpkin sold in America.

The 2022 corporate exodus still shadows the business climate debate. Within about two months that summer, Boeing moved its headquarters from Chicago to Arlington, Virginia, after two decades in the city; Caterpillar shifted its global headquarters and roughly 230 corporate jobs from suburban Deerfield to Texas while keeping its Illinois manufacturing; and Ken Griffin, then the state's richest resident, announced Citadel's move to Miami, citing crime and frustration with state political leadership. The counter-ledger has filled in since. Rivian rolled the first R2 SUV off its Normal assembly line on Earth Day in April 2026, the product of a $1.5 billion expansion backed by state REV Illinois incentives, with capacity for 155,000 R2s a year when fully scaled and a new $120 million supplier park linked to the plant by a tunnel under U.S. 150. Stellantis, under its deal with the UAW, has committed to reopening the shuttered Belvidere assembly plant in 2027 to build a new midsize pickup, restoring about 1,500 union jobs. And the quantum park rising at South Works has drawn IBM, Infleqtion, Diraq, and a DARPA proving ground alongside PsiQuantum, with a completion target of 2028.

Two regulatory clocks tick under all of it. The 2021 Climate and Equitable Jobs Act requires private coal- and oil-fired power plants to close by January 1, 2030, and gas plants by 2045, on the way to 100 percent carbon-free power — with carve-outs for Springfield's city-owned Dallman station and the municipally owned Prairie State campus, among the nation's largest coal-plant carbon emitters, which must cut emissions 45 percent by 2035 and hit zero by 2045. The same law subsidized the state's six nuclear plants, more than any other state, which supply about half of Illinois's electricity. In Chicagoland, a $771 million transit "fiscal cliff" was averted when the legislature passed the Northern Illinois Transit Authority Act in the early hours of October 31, 2025, directing roughly $1.5 billion a year to CTA, Metra, and Pace and replacing the RTA with a new authority, NITA, that stands up in September 2026 with power to set unified fares.

The Political Character

For its first 175 years, Illinois was the country's mirror. It voted Republican in every presidential election from 1952 through 1988 except 1960 and 1964, even rejecting Jimmy Carter in his winning 1976 campaign — and until 2000, no Republican had ever won the White House without carrying Illinois. George W. Bush broke that rule twice, because by then the state had flipped: Democrats have carried Illinois in every presidential election since 1992, each time by double digits. The engine was Cook County. Bill Clinton's 58 percent there in 1992 was the best Democratic showing since 1964; by 2004 John Kerry became the first nominee of any party to crack 70 percent in the county since Warren Harding in 1920, and Democrats stayed above that line for two decades.

The Akashic spine shows what happened inside the blowouts. Barack Obama's home-state 2008 landslide — 61.9 percent to 36.8, a 25.1-point margin — carried 46 of the 102 counties, including Macoupin in the old coal belt and Gallatin on the Ohio River. The floor then fell out from under downstate. The region outside Cook and the collars went from Obama +3.7 in 2008 to Romney +7.6 in 2012 to roughly Trump +19 in 2016, 2020, and 2024. Gallatin County swung 67 points in 16 years, from Obama +13 to Trump +54; Macoupin swung 49. By 2016 the Democratic county map had shrunk to 11; in 2020 and 2024 it was an identical set of 14 — Cook, the five collars minus McHenry plus Kendall, and the metro and campus counties of Champaign, McLean, DeKalb, Peoria, Rock Island, Winnebago, St. Clair, and Jackson. The collars moved the other way: DuPage, which Gerald Ford carried by 40 points in 1976, has voted Democratic for president in every election since 2008 and gave Kamala Harris a 13-point margin in 2024. Champaign County moved 7 points further left between 2008 and 2024 even as the state moved 14 points right.

The 2024 result is the finding. Harris won Illinois by 11 points — the narrowest Democratic presidential margin since 2004 — on a Republican share, 43.8 percent, the party's best since George W. Bush's 44.5 in 2004. Cook County still delivered a 42-point margin, but that was the county's weakest in the 2008–2024 series, Harris's 70.4 percent share its lowest, and Trump's 583,852 Cook County votes were the most any Republican drew there across those cycles. The wall held while eroding at both ends: downstate already gone, Cook softening. And the wall is what makes Illinois regionally singular — every one of its five neighbors voted for Trump in 2024, from Wisconsin's 0.9-point squeaker to Kentucky's 31-point rout, and among the large Midwest states, only Minnesota joined Illinois in the Harris column — Michigan and Ohio went the other way by 1.4 and 11.2 points.

State elections tell a different story on the same map. Pat Quinn held the governorship in 2010 by 19,413 votes — half a point — two years after Obama's 25-point romp. Bruce Rauner then won it for the Republicans in 2014 by 3.9 points, presided over a historic budget impasse, and in 2018 lost to JB Pritzker by 15.7 while drawing 38.8 percent, the worst showing for an incumbent Illinois governor since 1912. Pritzker beat Darren Bailey by 12.5 points in 2022 with the best Democratic raw percentage for governor since 1960. The federal layer is just as lopsided now: the congressional delegation runs 14 Democrats to 3 Republicans, and no Republican has won an Illinois U.S. Senate race since 2010.

The 2026 cycle is the structure made visible. Dick Durbin's retirement opened his Senate seat for the first time since 1996, and the March 17 Democratic primary became one of the most expensive in the country: Rep. Raja Krishnamoorthi raised more than $30 million and outspent Stratton on advertising by a reported $20 million-plus, yet Lt. Gov. Juliana Stratton won with about 40 percent to his 33, lifted by Pritzker's endorsement and at least $5 million he put into a supporting PAC. She faces Don Tracy, a former state GOP chairman, in November, and would become, by the Sun-Times's count, the state's fourth Black U.S. senator. Pritzker himself is seeking a third term — something no Illinois governor has managed since the 1980s, when James R. Thompson stacked up four consecutive wins — in a rematch against Bailey, who won the Republican primary with Cook County GOP chair Aaron Del Mar as his running mate. The primary campaigns were fought, by wide press consensus, over a single federal presence: the immigration crackdown that put Illinois at the center of the country's federalism fight.

The Texture

Start with the pizza, because the tourists get it wrong. Deep dish is the export; what Chicagoans order at the neighborhood spot is tavern-style — cracker-thin, party-cut into squares, a style usually credited to South Side institutions like Vito & Nick's in the 1940s, born as a salty bar snack to keep patrons drinking. The Italian beef — ordered in the local grammar of hot or sweet, dipped or dry — went national after the 2022 premiere of "The Bear," and in February 2026 a state representative from Evergreen Park introduced a resolution to crown it the official state sandwich, drawing immediate, only half-joking resistance on behalf of Springfield's horseshoe, the open-faced pile of meat, fries, and cheese sauce invented at the capital's Leland Hotel in the 1920s. Wash any of it down, if dared, with Malört, the wormwood liqueur that NBC Chicago calls the city's most notorious spirit.

The state's self-image got a referendum of sorts in 2025: a flag-redesign commission collected more than 4,800 proposed new designs, put ten finalists to a public vote against the current banner and two historic ones, and watched the existing flag win 43 percent of roughly 385,000 votes — more than the next five designs combined. Secretary of State Alexi Giannoulias conceded that some deride it as "a seal on a bedsheet" — and noted the public prefers it anyway. Downstate, autumn means the pumpkin harvest funneling into the Morton cannery — the state's least contested supremacy.

Fault Lines

The first fault line is the oldest: Chicago against the rest, with the collars as the swing weight. The official-sandwich fight is the comic version; the serious version is that the same General Assembly that averted the transit cliff for Chicagoland adjourned its spring 2026 session without passing the stadium-financing framework the Bears wanted, and on June 5 the team's board — for the first time in the saga — formally voted to advance a stadium in Hammond, Indiana, which would take a charter NFL franchise out of state for the first time in its 106-year history. The Bears say Arlington Heights, the 326 acres they bought for $197 million in 2023, remains alive if Illinois delivers property-tax certainty and roughly $855 million in infrastructure. Whether the franchise's address ends up in Cook County, the suburbs, or Indiana is the exit-anxiety debate — the Boeing, Caterpillar, and Citadel departures, the population-estimate wars — compressed into a single negotiation.

The second is Illinois against Washington. "Operation Midway Blitz," the federal immigration enforcement surge that began in the Chicago area in September 2025, brought hundreds of agents, the federalization of roughly 300 Illinois National Guard members, and 200 more guardsmen flown in from Texas. A federal judge, April Perry, blocked the troop deployment in October, finding "no credible evidence that there is danger of rebellion in the state of Illinois," and the Supreme Court ultimately sided against the administration; the Guard element ended December 31, 2025. The litigation has run in both directions since — another judge's limits on agents' use of force were vacated by the Seventh Circuit in March 2026, while a consent-decree judge found warrantless-arrest violations and ordered detainee releases that an appeals court paused. Pritzker, who called the deployment demand "outrageous and un-American," emerged as a national resistance figure with visible 2028 ambitions, and the confrontation set the emotional terms of the state's 2026 primaries.

The third is the corruption inheritance against the state's claims of reform — Madigan in a West Virginia prison camp is the freshest entry in a ledger that includes four governors. The fourth is demographic: a state finally adding people overall while shedding children faster than any other, which is a quieter threat to the tax base, the schools, and the legislature's long-term math than any single headline.

What to Watch

November 3, 2026, answers three measurable questions. Pritzker's margin against Bailey, against the 2022 baseline of 12.5 points, will show whether the off-year electorate matches the presidential erosion. Cook County's margin — D+42 in 2024, the modern low — is the single number that says whether the wall is stabilizing or still softening. And Stratton versus Tracy tests whether the Republican statewide drought, unbroken in Senate races since 2010 and in governor's races since 2014, survives an open-seat year. The dated clocks beyond the election: NITA assumes control of Chicagoland transit in September 2026; Belvidere's Stellantis line and its roughly 1,500 jobs are due back in 2027; the quantum park targets completion in 2028; private coal-fired power must be off the Illinois grid by January 1, 2030. Madigan's possible Supreme Court petition would decide whether the state's signature conviction of the decade stands as precedent or gets one more hearing. And somewhere between Arlington Heights and Hammond, shovels will eventually hit dirt — the most legible referendum yet on whether the things that define Illinois still have to be in Illinois. The state used to tell America how it would vote. The next two years will tell Illinois what it still holds.
