California GOP Rep. Young Kim advances to general election in state's 40th District

Incumbent California GOP Rep. Young Kim will advance to the November general election to defend her seat after successfully fending off a challenge by Republican Greg Raths – a retired U.S. Marine Corps colonel and combat fighter pilot.

Nearly one week after the California primary, the Associated Press called the race on Monday evening. 

Kim will face off in the fall against Democratic candidate Asif Mahmood, who won 47% of the vote in the district's top-two finisher system. Kim, 59, won 32% of the vote, while Raths wound up with 19%.

Kim, who now represents the state's 39th District, was forced to switch following the post-census redistricting effort. She now represents only about 20% of the Orange County district in which she is now running. 

The congresswoman won her last general election by a margin of 50.6% to 49.4%. Her seat is one that Republicans will fight to hang on to during the upcoming election.
