Republican incumbent David Valadao on Tuesday was projected to win a third House term, hanging on to his seat in California’s 21st Congressional District. 
Valadao, who defeated Democrat Emilio Huerta, had been considered one of the most vulnerable incumbents in California.

“No matter what I do, what event I do, if it’s a tele-town hall, if it’s a door-knock, doesn’t matter where I’m at, water is the first thing you hear about,” Valadao said in an interview according to news reports.
