California 22nd Congressional District

In Corcoran, the ground has fallen as much as eleven and a half feet since 2007. The town of roughly twenty thousand people sits on the floor of the old Tulare lakebed in Kings County, ringed by cotton and tomato fields and anchored by a maximum-security state prison that is one of the largest employers for miles. For decades the giant farming operations of the basin have pumped groundwater faster than any wet year can replace it, and the aquifer beneath the town has been collapsing in slow motion. Then, in the soaked winter of 2023, the lake that engineers drained a century ago came back. A relentless train of atmospheric rivers buried the Sierra Nevada under record snow, and the spring melt surged down the rivers and onto cropland that had not flooded in four decades. As it rose toward Corcoran, the levee that local property taxes and the prison system had paid to raise in 2017 was no longer tall enough, because the land it protected had kept sinking underneath it. The state poured seventeen million dollars into another round of levee engineering to keep the returning lake out of the town.

That is the literal version of this district's condition, and it is also the metaphor. California's 22nd is a seat on unstable ground in every sense. For president it backed Barack Obama, Hillary Clinton, and Joe Biden by double-digit margins across four straight elections — and then, in 2024, it moved 18.8 points toward the Republican candidate and flipped. All the while it kept sending the same moderate Republican to the House: David Valadao, a Hanford dairy farmer who was one of ten House Republicans to vote to impeach Donald Trump after January 6, and the only one of them Trump never targeted for revenge. It is a place that grows a large share of the country's food while breathing the nation's worst air, where roughly six in ten residents are enrolled in Medi-Cal, and where the modern farmworker movement was born in a Delano vineyard. And as of mid-2026 it is one of the most fought-over House seats on California's map, because the Legislature has just redrawn its lines to take it.

The ground

The 22nd is stitched from pieces of three southern San Joaquin Valley counties: most of Kings, plus slices of Tulare to the east and Kern to the south. It is not a city and not a county — it is a band of the valley floor that takes in the south side of Hanford, the prison town of Corcoran, the citrus-and-dairy towns of Tulare, Porterville, and Lindsay, the table-grape town of Delano, and a string of Kern farm communities — Wasco, Shafter, McFarland, Arvin, Lamont — before reaching the east side of Bakersfield. These are the places where the work of feeding California actually happens: the packing sheds, the dairies, the labor camps turned into towns, the two-lane roads that run dead straight between fields until they hit Highway 99 or Interstate 5.

The valley's defining feature is that it is a bowl. The Sierra Nevada wall it off on the east and the Coast Ranges on the west, and the air that settles into the basin has nowhere to go. Almond-harvest dust, dairy ammonia, diesel exhaust off the truck corridors, and winter wood smoke all pool against the mountains, which is why the American Lung Association has ranked Bakersfield the worst metropolitan area in the country for year-round particle pollution six years running, and worst for short-term particle spikes in three of its recent reports. The same geography that traps the smog also defines the water: every drop the district farms with is either pumped up from the sinking aquifer or carried down from the Sierra snowpack through a plumbing system of canals and reservoirs that the dry years strain to the breaking point.

And beneath all of it is the ghost of a lake. Tulare Lake once spread across the basin floor; nineteenth-century reclamation drained it for farming, and for most of the last century it existed only as a name on old maps and the faint outline of a lakebed. It returned most dramatically in 2023, for the first time in roughly four decades, when it grew nearly as large as Lake Tahoe and drowned thousands of acres — and the towns and farms of the basin are organized around the assumption that it will stay gone, an assumption that the ground is no longer cooperating with.

The arc

Two histories converge on this stretch of the valley, and the district prefers to tell one of them.

The one it tells is the farmworker movement. On September 8, 1965, Filipino American grape pickers in the Agricultural Workers Organizing Committee, led by Larry Itliong, walked off the table-grape vineyards around Delano. The walkout was part of a wave: a year earlier, organizers had finally won the end of the bracero program, which for two decades had let growers import Mexican guest workers as replacement labor, and its termination had touched off farmworker strikes across California. Two weeks in, Itliong's group persuaded Cesar Chavez and the mostly-Latino National Farm Workers Association to join, on Mexican Independence Day, and the two organizations eventually merged into the United Farm Workers. Chavez insisted the Filipino and Latino strikers share the same picket lines, kitchens, and union hall. The strike ran five years and rode a national grape boycott into history; California's table-grape growers finally signed contracts in 1970. At the Forty Acres, the union's headquarters outside Delano, Chavez fasted for twenty-five days in 1968, breaking the fast at a mass attended by Senator Robert F. Kennedy, who called him one of the heroic figures of the era. Delano is, in a real sense, where Latino political power in California learned to organize itself.

That history is not simple in 2026. As the district marked Chavez's birthday this spring, Delano residents found themselves divided over how to remember him in light of publicly reported allegations against him — a reckoning, attributed in national coverage, that has complicated the movement's central icon in the very town that holds his legacy.

The other history is the one the lakebed keeps. Before the cotton barons, Tulare Lake was the ancestral water of the Tachi Yokut people, who call it Pa'ashi. The reclamation that turned the lake into farmland was also a dispossession, and when the water returned in 2023 the Tachi Yokut held a ceremony at the new shoreline. As of mid-2026 the tribe and a coalition of environmental advocates are pressing a plan to permanently restore a portion of the lake and its wetlands near Kettleman City — a proposal to put water back on land that, under the state's groundwater law, is already being pulled out of farming. The drained lake and the dispossessed tribe are the counter-history beneath the orchards, and the basin's water crisis is quietly reopening it.

The people

This is a young, poor, heavily immigrant district, and almost every number in its demographic profile runs against the national grain. Its median age is 30.9, against 39.1 nationally. Hispanic or Latino residents make up about 60 percent of the population — Mexican ancestry alone accounts for roughly 52 percent — while non-Hispanic white residents are about 22 percent. The median household income is $60,377, well under the California figure of $99,122 and below the national median; the poverty rate is 22 percent, and child poverty is nearly a quarter. One in five adults holds a bachelor's degree, against more than a third nationally. Forty-five percent of residents speak a language other than English at home, overwhelmingly Spanish. Within the broad categories are sharper threads: a Filipino population that traces in part to the same labor migration that started the grape strike, and a notable Hmong community among the district's Asian residents.

What ties the demographics to the land is a paradox the district lives every day. The towns here help feed the country — the greater Central Valley produces a large share of the nation's food — and they pay for it with their lungs and their water. In Lamont, an unincorporated Kern County community where about 94 percent of residents are Hispanic and roughly a third live below the poverty line, the worst air in America is simply the weather. In dairy towns across the basin, families buy bottled water because farm operations have made the well water undrinkable. The dairy that anchors the local economy — and that the district's own congressman farms — is also, by the accounting of air regulators and the residents who file the complaints, one of the largest sources of the pollution. The people who grow the food are the ones most exposed to the cost of growing it, and that fact sits underneath the district's politics whether or not its politics ever names it.

The dairy farmer and the most-wanted seat

For a place that votes the way this one does at the top of the ticket, the 22nd has a remarkably durable Republican congressman, and understanding why is the whole key to the seat.

David Valadao is the son of Portuguese immigrants who started a dairy near Hanford in 1973; he runs dairy operations himself and came up through the California Assembly before winning a congressional seat in 2012. The seat he won that year was numbered the 21st, and he represented versions of it through two redistrictings and one defeat; only after the 2022 maps did his territory become the 22nd. He is not a generic Central Valley Republican. He voted against ending the Deferred Action for Childhood Arrivals program, breaking with his party on immigration, and he has publicly invited his party's immigration hardliners to spend a day with him among Central Valley farmworkers. He is firmly opposed to expanding abortion access. And in January 2021 he became one of ten House Republicans to vote to impeach Trump over the Capitol riot. Trump went on to endorse primary challengers against nearly every one of those ten — but not against Valadao, whom he conspicuously left alone.

The result is a congressman who runs ahead of his party's national brand in a district that runs behind it. The clearest illustration is 2020: Valadao won the seat back from Democrat TJ Cox by about 1,750 votes — roughly two points — in the same election in which Joe Biden carried the district by ten. Two years earlier, in the 2018 blue wave, Valadao had been the one to lose, falling to Cox by 862 votes, a defeat some analysts tied to his vote to repeal the Affordable Care Act in a district where health coverage is existential. He clawed it back and held it through two rematches with Democrat Rudy Salas, in 2022 and 2024. The pattern is consistent: the district's voters will split their ballots to keep a known local dairy farmer even as they vote against his party for president.

That over-performance is exactly what California's Democrats set out to neutralize. In response to Texas's mid-decade Republican gerrymander, Governor Gavin Newsom and the Legislature put Proposition 50 on the November 4, 2025, ballot, asking voters to replace the state's independent-commission congressional map with legislatively drawn lines for 2026, 2028, and 2030. Voters approved it. The new lines do not erase the 22nd, but they nudge it bluer — by outside estimates, from a seat Trump carried by about six points to one he would have carried by under two — and hand Democrats a clear registration advantage. The wrinkle is one of timing: the new districts do not take effect for representation until January 2027, so Valadao finishes this term in his old district, but the 2026 primary and general are run on the new lines. Whoever wins in November represents the redrawn seat.

The contest those new lines produced is its own story. In the June 2, 2026, top-two primary, Valadao again finished first and advanced, as expected. The fight was for second place, and it was a proxy battle for the national Democratic Party's argument with itself. On one side was Assemblymember Jasmeet Bains, a Delano physician and the centrist in the race; on the other, Randy Villegas, a College of the Sequoias political science professor and Visalia school board trustee running as a Bernie Sanders-endorsed progressive. The state party, deadlocked, declined to endorse either of them, and the national party's campaign arm — after promising to stay out — broke late for Bains, drawing public protest from House progressives. As one chronicler of the race put it, the primary embodied the larger tug-of-war over how Democrats win back the voters they lost in 2024 — by playing to the center, as the party's winning gubernatorial candidates did in New Jersey and Virginia, or by adopting the economic populism that lifted New York's mayoral race. Then Villegas, the progressive the national party had passed over, edged Bains for the second slot. He will face Valadao in November, on a map drawn to make the dairy farmer's long defiance of political gravity finally too heavy to sustain — though, as one handicapper cautioned, the district is itself trending Republican, and it is likely to be a battleground regardless of the map.

The vote

A word on the lines before the numbers. The presidential series on this page is computed on a single fixed footprint that the page labels "current," and the 2024 result it shows — Trump by 1.8 points — corresponds to the new Proposition 50 lines rather than to the 2022 commission lines on which the seat was actually contested last cycle. On those older lines, by outside reporting, Trump carried the district by about six points in 2024 while Valadao won the House race by roughly seven (a margin the House table here records as R+6.8). The distinction matters for attribution, but it does not change the shape of the trend, which is dramatic on any consistent set of lines: this district moved hard to the right between 2020 and 2024.

Read the presidential numbers and the striking thing is how stable the Democratic share was, right up until it wasn't. The Democratic presidential candidate took 54.6 percent in 2008, then 57.8, 57.6, and 57.4 percent across the next three elections — a flat plateau just under 58 percent through Obama, Clinton, and Biden, producing margins that ran from D+10.3 in 2008 to a high of D+20.6 in 2016. Then 2024 broke the floor. The Democratic share fell to 47.8 percent — a drop of nearly ten points in a single cycle — and the seat went R+1.8.

What moved is not a third-party story. Across the whole series, support for minor candidates never rose above the 5.5 percent of 2016 and sat at 2.7 percent in 2024, so the collapse was a straight two-way swing. Decompose it: between 2020 and 2024 the Democratic share fell 9.6 points while the Republican share rose 9.3, almost a mirror image. The raw votes tell the same story in a sharper register. The Democratic vote total fell from 108,980 to 81,816 — a loss of more than 27,000 votes, nearly a quarter of the party's support — while the Republican total rose from 76,614 to 84,924, and overall turnout dropped almost ten percent. So 2024 in the 22nd was two things happening at once: a real shift of working-class Latino voters toward Trump, and a steep falloff in Democratic turnout. Both are necessary to explain a near-nineteen-point move.

Underneath the presidential swing runs the crossover gap that defines the seat. Even in 2020, when the district's presidential vote was D+17, its House seat stayed Republican. The 22nd has spent more than a decade voting one way for president and another for the House, and the size of that gap — large enough to survive a Biden landslide — is the single most important fact about its politics. It is what made Valadao durable, and it is what Proposition 50 is designed to overwhelm.

What to watch

The November 2026 general is the first real test of whether the over-performance survives the new map. The question is mechanical and specific: Valadao's brand has been worth a substantial ballot-splitting premium — enough to win a seat Biden carried by ten — but the redraw both subtracts friendly precincts and arrives in a cycle when the district itself is drifting his party's way. Whether his personal margin can still clear a line drawn to erase it is the cleanest version of the national crossover-incumbent question, and the 22nd is where it gets answered.

Watch the water, because it sets the terms of everything else. Under the 2014 Sustainable Groundwater Management Act, the basin's pumping has to reach sustainability by 2040, and the state has already taken the unprecedented step of placing the Tulare Lake subbasin on probation for inadequate plans — a move that could force the largest agricultural pumpers to meter their wells and pay fees, and that the growers are contesting in court. Every acre fallowed to meet those limits is a job and a tax base subtracted from towns that have little to spare, and the fight over how much farmland comes out of production — and whether some of it becomes restored lake instead — will shape the district's economy more than any single election.

Watch health coverage. In a district where roughly six in ten residents rely on Medi-Cal, federal decisions about Medicaid funding land harder here than almost anywhere, and the issue cuts directly against the incumbent's party even as the incumbent himself has built a record of breaking with it. It was, after all, a health-care vote that some credit for his only defeat.

And watch the demographic engine. The 22nd is young, heavily Latino, and growing, with a large share of residents who are not yet citizens but whose children are. How that rising electorate breaks — whether 2024 was a one-time shock driven by turnout and inflation or the start of a durable Latino realignment toward the Republican Party — will decide far more than one seat. This district is one of the places that will tell the country which it was.

The unstable ground

The levees around Corcoran are taller now, and the lake has receded again, and the farms are back on the lakebed for the time being. But the aquifer is still falling, the groundwater clock is still running toward 2040, and the politics are no steadier than the soil. California's 22nd has voted for Democratic presidents and a Republican congressman, flipped to Trump and elected the Republican who impeached him, fed the country and choked on the cost — and it has now been redrawn by one party precisely because the other party's man would not stop winning it. The only safe prediction for the seat on sinking ground is that it will not hold still.
