An expensive Democratic civil war is brewing this election cycle, with a staggering 30 House Democrats facing at least one primary challenger who has raised $100,000 or more, an Axios analysis found.

Why it matters: These primaries are drawing tens of millions of dollars from Democrats' efforts to retake the House while priming House Minority Leader Hakeem Jeffries (D-N.Y.) to inherit a rebellious class of new freshmen.

The collective fundraising in these races adds up to more than $64 million — out of roughly $500 million raised by all Democratic House campaigns so far this cycle.
Nearly a dozen House Democrats are facing primary challengers who have raised more money than they have.
Many of these primary insurgents — along with a huge cohort of outsiders and progressives running in open primaries — have declined to commit to supporting Jeffries' leadership if elected.

Flashback: Contrast that with the 2018 election cycle, in which progressives rode a wave of grassroots energy spurred by Bernie Sanders' presidential campaign two years earlier to make huge gains.

2018 was the year Reps. Alexandria Ocasio-Cortez (D-N.Y.) and Ayanna Pressley (D-Mass.) unseated veteran Democratic incumbents.
But just half a dozen Democratic primary challengers ended 2017 having raised $76,000, the CPI-adjusted equivalent of $100,000 that year.

What they're saying: "Typically what I do with my money is send it to the districts that need it," Rep. John Larson (D-Conn.) told Axios.

With a fierce primary battle on his hands, he said, "that money doesn't go to the swing districts. ... We'll probably spend, in that primary, $5 million. Last year I probably spent more like $400,000."
A House Democrat close to leadership, speaking on the condition of anonymity, griped to Axios: "This is the new reality we live in, where people do not care about the party and trying to win."
"They just care about moving their ideological wing of the party forward," the anonymous Democrat said.

Between the lines: Unlike in past cycles, it's not simply a clash of the left versus the center.

Many of the incumbents who are facing the fiercest primary challenges are over 70 years old, with younger rivals calling for generational change.
Some Democratic insurgents are also criticizing the party establishment for not "fighting" Republicans hard enough, a stylistic but relatively non-ideological complaint that has dominated the party's grassroots politics over the last year.

What we're hearing: These candidates "don't care what Hakeem thinks, they care what AOC may think," said the House Democrat close to leadership.

"That's the problem, and then you end up spending a fortune," the lawmaker said, arguing that the Democratic Congressional Campaign Committee should defend safe-seat incumbents in primaries.
"In this new world, they're going to have to do that. Because it's bullsh*t otherwise, why would anyone want to pay their dues?"
"I'd be frustrated too," said a senior House Democrat. "It's like, 'I've been giving you money to support frontliners.'"

The other side: "That these primaries are happening at all is a sign that the establishment such as it still exists has lost control," said Amanda Litman, founder of Run for Something.

"In the past, they might have been able to credibly box out challengers or clear the field; in 2026, the old guard simply doesn't have the juice anymore."
She added: "I think the party will be better off for it — incumbents having to defend their leadership and make an affirmative case for how they're the best people to lead us forward helps sharpen our arguments."

What to watch: March 3 primaries in North Carolina and Texas will be the first test for embattled Democratic incumbents.

Rep. Valerie Foushee (D-N.C.) is facing a well-funded challenge from left-wing rival Nida Allam, who is backed by Sen. Bernie Sanders (I-Vt.).
Longtime Rep. Al Green (D-Texas) is battling with newly-elected Rep. Christian Menefee (D-Texas) for a single Houston-based seat, while Rep. Julie Johnson (D-Texas) is being challenged by former Rep. Collin Allred.

The bottom line: The blue wave Democratic leadership is praying for may turn out to be a double-edge sword, sweeping them into power while putting them at the mercy of a group of insatiable rabble rousers.

Jeffries need only ask former Speaker Kevin McCarthy how that went.
