California is the largest prize in American politics — 54 electoral votes and 52 U.S. House seats, carried by the Democratic candidate in every presidential election since 1992. In November 2025 its voters approved Proposition 50, replacing the state’s independent-commission congressional map with a legislatively drawn one expected to add about five Democratic seats — Governor Gavin Newsom’s answer to a mid-decade Republican redraw in Texas. The fight lifted Newsom, term-limited in 2026, to the front of the early 2028 Democratic field.
Yet California moved toward Donald Trump in 2024 nearly as fast as anywhere — a nine-point drop in its Democratic margin, from 29 points in 2020 to 20, the fourth-largest shift of any state. The move ran deepest in the heavily Latino interior: Imperial County, 86 percent Hispanic, gave Hillary Clinton a 42-point margin in 2016, then flipped to Trump by 2024 — a reversal of more than 40 points in eight years. The Central Valley counties of Merced, Tulare, and Fresno each moved double digits. By Akashic’s analysis the swing tracked the state’s immigrant geography — the communities that give California the highest share of non-English-speaking households in the country, 44 percent — part of a national shift among Latino voters.
The state is unlike any other in scale and mix: 39 million people, a Hispanic plurality at 40 percent and 15 percent Asian, with non-Hispanic White residents about a third. It is wealthy, with a median household income of $99,122, fifth-highest in the nation, and Catholic where it is religious, at 26 percent — though a 55 percent unaffiliated majority leaves it among the least religiously affiliated states. No single group is a majority.
