It’s still very, very early, but Democratic Rep. Pete Stark is currently about 200 votes short of his Democrat challenger, Eric Swalwell.
Stark has been in Congress since 1973. According to Wikipedia, he is the fifth most senior member of the U.S. House of Representatives.
Maybe California has finally had enough.
Update: Stark has pulled ahead and is now leading Swalwell by several thousand votes. Sigh.
