It is the birthplace of Richard Nixon and modern conservatism but Orange County, California now firmly belongs to Democrats.
Gil Cisneros has defeated Young Kim, a Republican, to capture a fourth seat in what had once been one of the most conservative Republican bastions in the nation.
The victory by Cisneros completes what has amounted to a Democratic rout in California this year.
Democrats set out to capture seven Republican-held seats where Hillary Clinton defeated President Trump in 2016, including four in Orange County. They won six of them.
Representative David Valadao, from the Central Valley, is the only Republican who survived the Democratic onslaught in those seven districts.
His margin has shrunk as mail-in votes have continued to be counted. The deadline for counting those votes in California is Dec. 7.
With Cisneros’s victory, Democrats now control all four House seats in Orange Count.y.
The party also won supermajorities in the California Assembly and Senate, while the party’s candidate for governor — Gavin Newsom, the lieutenant governor — easily turned back a Republican challenge. Democrats control every statewide elected position in California.
