IRVINE, Ca. — Progressive Democrats are bracing for tens of millions of dollars in campaign ads from pro-Israel groups to rain down on them in this year’s primaries. They’re a little surprised about where it started — a stretch of Orange County where neither Democratic candidate is calling for a Gaza ceasefire.

In California’s 47th congressional district, which Rep. Katie Porter is leaving to run for the U.S. Senate, the American Israel Public Affairs Committee’s campaign PAC has gone all-in to beat state Sen. Dave Min in Tuesday’s primary. As of Thursday, according to the United Democracy PAC’s FEC filings, it’s spent $4.6 million to pummel Min, the vast majority of its ads and mailers focusing on his May 2023 arrest for driving under the influence.
