The seat in the Southern California district is now held by retiring GOP Rep. Darrell Issa.

Levin consistently outraised opponent Harkey, who was endorsed by President Donald Trump.

Democrat Mike Levin, an environmental attorney, is the apparent winner of California’s 49th Congressional District seat being vacated by retiring 10-term GOP Rep. Darrell Issa, according to NBC News.

Levin beat Republican Diane Harkey, a conservative state official who had been running behind in recent polls. She was endorsed in August by President Donald Trump.

The district, which Hillary Clinton carried by 8 points in the 2016 presidential election, covers several communities along the Southern California coast from Dana Point in Orange County to Del Mar in San Diego County. Besides taxes, jobs and health care, immigration and the environment were top issues in the race.

Levin consistently outraised Harkey, and in the third quarter he reported doing so by a nearly 4-to-1 margin. Two polls conducted in September showed Levin with a double-digit lead over Harkey.
