Is Jan. 6 a Winning Political Issue in California? We’re About to Find Out.

Rollins’s largest donors are three PACs focused on L.G.B.T.Q. issues, including the political wing of the Congressional L.G.B.T.Q.+ Equality Caucus, which donated $5,000 and endorsed his campaign. More than $145,200 of his war chest came from people who gave less than $200.

Take Back the House 2022, a joint fund-raising committee led by Republican leaders, has given $95,575 to Calvert. Corporate PACs, including those affiliated with Northrop Grumman, Booz Allen Hamilton and Raytheon, are also among Calvert’s biggest financial supporters.

Through a campaign spokesman, Calvert declined an interview, but emailed a statement.

“Riverside County families are confronting a number of challenges in their daily lives,” he said. “Between record-breaking gas prices, high food costs, and baby formula shortages, most of these challenges were created under President Biden’s failed leadership.”

“I have consistently spoken out against political or any other kind of violence,” he added.

Although national Republicans say they aren’t worried about Calvert, the new 41st District has become more Democratic. It now includes Palm Springs, a left-leaning city that Rollins has made his base. And for the first time, it contains more registered Democrats than Republicans. The area voted for Trump by just one percentage point in 2020.

Official Democratic Party groups, daunted by President Biden’s low approval ratings and by a national map that is forcing them to defend dozens of seats, have yet to show interest in the race.

But Rollins has drawn about $65,000 in support from Welcome PAC, a relatively new Democratic-aligned outfit that applies insurgent tactics to support center-left candidates in swing districts.

Liam Kerr, a founder of the group, said that Rollins was the committee’s first major investment because Calvert had rarely faced a serious challenge, and because the district ought to be winnable for the right Democratic candidate.
