Congressman Jeff Denham has conceded his defeat to Democrat challenger Josh Harder.

According to the California Secretary of State’s website, Harder won with 6,605 more votes than Denham. The latest unofficial count has Harder with 106,200 votes, or 51.6 percent, to Denham’s 99,595 votes, or 48.4 percent.

It was Denham’s first-ever defeat of a political career that saw his election to the state Assembly in 2000, victories for the State Senate in 2002 and 2006, survival of a Democrat-led recall effort in 2008 and four elections to Congress.

The 10th Congressional District has increasing turned blue in recent years. In 2016 Denham defeated Michael Eggman by a margin of 110,659 to 100,646 votes.

“Pam and I want to thank the people of our community for the humbling privilege to serve you in Congress,” Harder said in a statement, calling the campaign “hard fought” and also thanking Denham for his service in the Air Force and in Congress. “I want to thank the unprecedented grassroots effort that supported this campaign — people who knocked on doors, made phone calls and worked so hard on this race.”

In the 12th District state Senate race, Anna Caballero defeated Republican Rob Poythress in a 100,353 to 87,267 vote outcome. Caballero, who is presently a member of the California State Assembly, will succeed Anthony Cannella, R-Ceres, who is being termed out of office.

State Assemblyman Adam Gray, D-Merced, easily won re-election over libertarian candidate Justin Ryan Quigley in the 21st Assembly District. Gray received 68,085 votes, or 71.1 percent of the vote, to Quigley who had 27,630 votes, or 28.9 percent.

Votes are still being processed. The official count is due on Dec. 6.
