The House race for California's 39th district has been called for Democrat Gil Cisneros over Young Kim, who was vying to become the first Korean-American woman in Congress and Republicans' last hope to keep a seat in Orange County. It is the 39th House seat that Democrats flipped this year.

The big picture: Democrats dominated congressional races in the state this year, flipping six seats with four of them in traditionally red Orange County. The seat had been held by Republican Ed Royce for 13 terms.
