California's reputation as a politically liberal state is being tested in a string of U.S. House districts that are expected to play into control of the chamber. Both parties see it as a crucial battleground and are pumping millions of dollars into contests in Southern California and the Central Valley farm belt. Two years ago the state played a pivotal role in securing the gavel for Republicans. California has 52 House seats, more than any other state. A handful of those are considered toss-ups. Democrats are dominant and hold every statewide office. But Republicans retain pockets of strength and picked up four House seats in 2020.
