25th District

Matchup: Rep. Steve Knight (R) vs. Bryan Caforio (D)

Dynamic: The freshman Republican is considered California’s most vulnerable Republican incumbent. He had a rocky start in Congress, getting caught on tape threatening a protester who confronted him over the issue of immigration. Demographics in this district suggest high Democratic turnout for the presidential race could be enough to oust Knight. First-time candidate Caforio, a UCLA and Yale graduate, is a trial lawyer. Race rating: Favored Republican

Interesting fact: Knight’s father, the late William J. “Pete” Knight, was a former Air Force test pilot and Republican state senator in the Antelope Valley.
