According to the Princeton Gerrymandering project, California's districts are better than average, with some bias. You can see a map of the entire U.S. on their front page.

Before the recent wave of gerrymandering started by Texas, California had an independent, non-partisan redistricting committee.

Could you provide a source for the claim that before 2025, there was significant gerrymandering in California?

As I said about civil liberties, there is a perception that Democrats are the lesser of two evils, given the realignment of the parties around segregation and civil rights in the 1960s. The Dixiecrats who were in favor of segregation left the Democratic party, while Republicans who favored racial integration joined the Democratic party. Then the Republican presidential campaigns of Goldwater, Nixon, and Regan shifted the party line to appeal more to the former Dixiecrats in the South. I'm agnostic about which party is better on civil liberties in 2025; I'd be interested in any research on the topic.
