The GOP hasn’t been able to regain its financial footing since it lost its key fundraiser: former House Speaker Kevin McCarthy.

According to federal campaign finance records reviewed by The Daily Beast, McCarthy’s successor, Mike Johnson, still has a long way to go before he’s shoring up the same amount of dough. That poses a major risk to vulnerable House Republicans—17 of whom will find themselves running for reelection come November in districts that swung toward Joe Biden in 2020.

While Johnson’s fundraising constitutes a fraction of what McCarthy raised for the caucus, the starkest difference can be seen by examining fundraising numbers for members of the National Republican Congressional Committee’s Patriot Program, which was designed to help the most vulnerable incumbents, according to the Beast. Funds for Arizona Representative Juan Ciscomani, for example, have taken a huge nosedive. In the first three quarters of 2023, Ciscomani received approximately $145,000 per quarter as directed by McCarthy, before he was given the boot. But in the last two quarters, under Johnson’s leadership, the freshman lawmaker has received an average of just under $14,000.

And with all the House seats up for reelection in November, this is arguably the worst time for the coffers to be running dry. Part of the reason for the lackluster numbers, however, may be outside of Johnson’s control. According to one GOP donor who spoke with the outlet, vacating McCarthy made a lot of conservative donors with open wallets “really, really angry”—which they ended up taking out on his successor.

While describing McCarthy as a “money machine,” GOP donor Eric Levine told the Beast that donors were going to take out his downfall “on whoever was next.”

Johnson, meanwhile, has openly acknowledged the predicament.

“Since October, Speaker Johnson has built a team from the ground up, traveled to 25 states, and contributed millions directly to Republican campaign accounts across the country,” a spokesman for Johnson’s campaign told the outlet. “His most recent quarter with over $20 million raised demonstrates the Speaker’s success and commitment to growing the majority.”

McCarthy, on the other hand, is still plying those fundraising skills—for revenge. One of his close allies is trying to recruit primary challengers to the eight Republican representatives who voted to oust him in October. And McCarthy is more than ready to mobilize his donor network to fund those challenges.
