WASHINGTON _ Rep. Jeff Denham, R-Calif., won his primary Tuesday _ but with 37.7 percent.
He did finish well ahead of Josh Harder, a Democrat who took about 16 percent of the vote and ran second in the 10th Congressional District, narrowly scraping past Republican Ted Howze.
But Denham's total was 10 points lower than his 2016 primary vote, and 20 points less than his 2014 primary showing.
