California

Dianne Feinstein, ranking member of the Committee on the Judiciary, is seeking a fifth full term. Because of the way that California primaries work, the top two candidates in the primary, regardless of party affiliation, advance to the general election. As such, California will remain in Democratic hands after November, as the election is between Dianne Feinstein and Kevin De Leon. De Leon has mounted a progressive challenge to Feinstein, but as a popular 26 year incumbent, it is unlikely that she will be voted out of her seat.
