All but three Democrats in California’s congressional delegation have now publicly backed Rep. Michael M. Honda’s re-election bid.

The six-term incumbent faces what will likely be a competitive primary in the Silicon Valley. Former Obama administration official Ro Khanna entered the 17th District race last week.

Thirty-three California Democrats endorsed Honda on Thursday in the latest boast of strength from the congressman’s campaign. He’s previously rolled out the endorsements of President Barack Obama, the state’s two senators and House Minority Leader Nancy Pelosi.

The three Democrats who have not endorsed Honda are Reps. Anna Eshoo, Susan A. Davis and Eric Swalwell, who knocked off the dean of the delegation, Pete Stark, in November. California’s top-two primary allows for the possibility that two members of the same party face off in the general.

Khanna had $1 million in cash on hand as of Dec. 31 after opening a federal account last cycle in preparation for a bid. For a first-time House candidate, Khanna wields an impressive campaign team and “executive committee” laced with Obama strategists and fundraisers.

Neither candidate had filed a first-quarter fundraising report as of Thursday evening. Campaign financial reports covering the first three months of the year are due Monday.
