Congressman David Valadao, R-Hanford, is one of seven California Republicans being targeted by state and federal Democratic groups with grassroots organizing and media buys.

Valadao won his race for the 21st Congressional District in 2016 but district voters voted for Democratic presidential candidate Hillary Clinton over President Donald Trump.

These groups see this as proof they can flip the 21st District to a Democrat.

Jeb Fain of the House Majority PAC said the group will target Valadao — and the six other California Republicans — with a mix of paid media and grassroots organizing.

The difference in 2018 will be that Valadao’s vote in support of the House version of the Affordable Care Act repeal bill shows him to be working against the interest of his own constituents, Fain said.

So far, Emilio Huerta, who ran unsuccessfully against Valadao in 2016, has thrown his hat into the ring against Valadao next year.

Fain said the Majority PAC effort is designed to inform voters about Valadao’s record in advance of the 2018 elections.

Jeff Denham, Steve Knight, Ed Royce, Mimi Walters, Dana Rohrabacher and Darrell Issa are the other members of Congress who have been targeted by the House Majority PAC.

Valadao’s campaign staff brushed aside the Majority PAC effort.

"Nancy Pelosi and her personal super PAC still haven't learned that their messaging, funded by Bay Area environmentalists, doesn't work in the Central Valley. Congressman Valadao will continue to focus on representing his constituents,” said Cole Rojewski, spokesman for Valadao for Congress.

Valadao has won the past three elections by large margins against Democrats, despite a striking voter registration advantage that Democrats hold over Republicans in the 21st District.

In addition to the Majority PAC, the California Red to Blue program has put Valadao on its target list.

The chair of the Red to Blue program, according to the group's website, is Michael Eggman, who ran unsuccessfully against Rep. Jeff Denham, R-Turlock, in the past two elections cycles.
