Several undecided U.S. House races in California remain too close to call, as ballots continue to be counted.

HUNTINGTON BEACH, Calif. (AP) — Several undecided U.S. House races in California remain too close to call, as ballots continue to be counted.

All of those districts are held by Republicans, and they were targeted by Democrats after Hillary Clinton carried them in the 2016 presidential election.

In the 45th District in Orange County, Republican Rep. Mimi Walters was holding a 1-point edge over Democrat Katie Porter on Saturday, a margin unchanged from a day earlier. Walter's edge was about 2,000 votes, with about 212,000 votes counted.

In the nearby 39th District, Republican Young Kim was in a close contest with Democrat Gil Cisneros. She was holding a 2,400-vote lead, or about 1.4 percent, with about 173,000 votes tallied. The seat is held by retiring Republican Rep. Ed Royce.

In the state's farm belt, Democrat Josh Harder was holding a narrow edge over Republican Rep. Jeff Denham in the 10th District. Harder had a 3,300-vote lead, with 177,000 votes counted.
