Several Democrats representing conservative-leaning districts are facing serious primary threats from their left flank after voting against — or initially opposing — a War Powers Resolution aimed at halting President Trump’s military strikes on Iran without Congressional authorization. Four House Democrats voted against the resolution outright: Reps. Jared Golden of Maine, Henry Cuellar of Texas, Greg Landsman of Ohio, and Juan Vargas of California. Their votes put them squarely at odds with 89% of Democratic voters who say the U.S. should not have attacked Iran, and progressive organizations are already lining up challengers.
The fallout is not hypothetical. Reps. Jared Moskowitz of Florida and Josh Gottheimer of New Jersey, who initially opposed the resolution before reversing course, are already facing primary challengers running in part on their hawkish stances. MoveOn has warned that “all options are on the table” for members who refused to act, and a senior progressive House Democrat told Axios that “several progressive groups will primary anyone” who voted no. Across the caucus, 30 House Democrats now face at least one primary challenger who has raised over $100,000, fueling what Axios described as a $64 million midterm civil war that is infuriating party leadership. This article breaks down who voted against the resolution and why, which primary challenges are already underway, how centrist Democrats are trying to thread the needle with alternative proposals, and what this all means for the 2026 midterms.

Which Red State Democrats Voted Against the Iran War Powers Resolution and Why?
Four House Democrats broke with their party to vote against the War Powers Resolution introduced to halt Trump’s military operations against iran. Rep. Jared Golden, who holds what is widely considered the reddest district in the country held by a Democrat, voted no — a decision consistent with his pattern of breaking from the party on national security issues. Rep. Henry Cuellar of Texas justified his vote by stating that “Congress must exercise oversight responsibly while ensuring our military can protect American lives and interests.” Reps. Greg Landsman of Ohio and Juan Vargas of California also voted against the measure. The common thread among these members is geography.
They represent districts where support for military action — or at least skepticism of anything that looks like restraining the commander-in-chief — runs higher than in coastal liberal strongholds. For these Democrats, the calculus has traditionally been that breaking with the party on defense issues insulates them in general elections. But the Iran conflict has scrambled that math. With nearly nine in ten Democratic voters opposing the strikes, these members now face a two-front political war: a general election where they need moderate and conservative voters, and a primary where the base is furious. The distinction matters because this is not a standard policy disagreement. War powers votes carry enormous symbolic weight. For progressive voters and activist organizations, a vote against the resolution was not a nuanced policy position — it was a vote to let a president they deeply oppose wage war without accountability.
Which Democrats Already Face Primary Challengers Over the War Vote?
The most concrete primary threats are materializing against members who were seen as wavering before the vote. Rep. Jared Moskowitz of Florida initially opposed the war powers resolution but later reversed his position. Despite the reversal, he now faces Oliver Larkin, a democratic socialist challenger who is running partly on Moskowitz’s hawkish posture. The reversal itself became a liability — progressive voters saw it as evidence that Moskowitz only changed course under political pressure, not out of conviction. Rep.
Josh Gottheimer of New Jersey followed a similar trajectory, initially opposing the resolution before switching his vote. He faces Nick Gebo in the NJ-5 Democratic primary. Gottheimer has long been a target of the party’s left wing for his centrist positioning, and the Iran vote gave challengers a concrete, emotionally charged issue to organize around. However, it is worth noting that primary challenges against incumbents rarely succeed, and not every challenger with a compelling message has the infrastructure to win. The more immediate danger for some of these members may not be losing a primary outright but being weakened enough that they become vulnerable in the general election. This is exactly the scenario Democratic leadership fears with Jared Golden in Maine, where state auditor Matt Dunlap is challenging him from the left. Party leaders worry that a bruising primary could cost them the seat entirely in a district Trump carried comfortably.
The $64 Million Democratic Civil War Reshaping the 2026 Midterms
The Iran vote did not create the Democratic Party’s internal tensions — it accelerated them. According to Axios, 30 House Democrats face at least one primary challenger who has raised at least $100,000, creating a $64 million midterm civil war. that figure represents real organizational capacity, not just protest candidacies. These are campaigns with donor networks, staff, and the ability to run television ads. The scale of this intraparty conflict is infuriating Democratic leadership under Hakeem Jeffries, who is trying to flip the House in 2026.
Every dollar spent in a primary is a dollar not spent against a Republican opponent. Every attack ad a Democrat runs against a fellow Democrat becomes opposition research for the eventual GOP challenger. Leadership’s frustration is understandable from a tactical standpoint, but the progressive base views the primaries as essential accountability. MoveOn made its position explicit, warning that its members “have no plans to throw their support behind members of Congress who refused to do their job and stop Trump from expanding his war. All options are on the table.” That language — “all options” — signals not just primary challenges but potentially withholding endorsements, volunteer hours, and small-dollar donations from incumbents who survive their primaries but still need progressive enthusiasm in November.
How Centrist Democrats Are Trying to Split the Difference on Iran
Rather than simply voting no and absorbing the political hit, a group of centrist Democrats attempted a middle path. Reps. Gottheimer, Landsman, Golden, Cuellar, Costa, and Panetta introduced an alternative resolution that would give the Trump administration 30 days to end hostilities with Iran, rather than the immediate halt demanded by the Khanna-Massie resolution that most Democrats supported. The 30-day approach was designed to let centrists claim they supported Congressional oversight while avoiding the appearance of pulling the rug out from under active military operations. For members in competitive districts, this framing — “responsible oversight, not reckless retreat” — polls better than an outright demand to cease operations immediately.
It gives them a talking point in both the primary and the general election. The tradeoff is credibility with the base. Progressive voters and organizations largely dismissed the alternative resolution as a delay tactic that would allow the administration to continue strikes for another month while running out the political clock. From the progressive perspective, if you believe the military action is unauthorized and unconstitutional, giving the president 30 more days to wage it is not oversight — it is complicity with extra steps. This fundamental disagreement over what constitutes meaningful Congressional action on war powers is unlikely to be resolved before primary day.
The Senate Stalemate and What It Means for House Democrats
The Senate added another layer of complication when it failed to advance its own Iran war powers resolution. Senate Republicans resisted calls for war hearings entirely, creating a new standoff with Democrats who wanted formal debate on the military action. The Senate’s failure to act effectively killed any chance of a war powers resolution reaching the president’s desk, regardless of what the House did. This creates a perverse dynamic for House Democrats who voted against the resolution. Their vote was, in practical terms, consequence-free from a policy standpoint — the resolution was not going to become law even if it passed both chambers with overwhelming support, given the likelihood of a presidential veto. But it was enormously consequential politically, because it became a litmus test.
Progressive groups do not evaluate members based on whether their vote changed the outcome. They evaluate members based on where they stood when it mattered. The limitation here is important to acknowledge: war powers resolutions are largely symbolic exercises in the current political environment. No president of either party has fully conceded Congress’s authority to constrain military action since the War Powers Act was passed in 1973. The real power Congress holds is the power of the purse — the ability to defund military operations. That is a far more dramatic step that almost no one in either party is currently proposing, and it would carry its own severe political risks.
What Progressive Organizations Are Doing Beyond Primary Challenges
The response from progressive organizations extends beyond simply recruiting and funding primary challengers. Groups like MoveOn are signaling a broader withdrawal of institutional support from Democrats they view as insufficiently opposed to the Iran conflict.
In practical terms, this means potential loss of volunteer networks, phone banking operations, digital advertising support, and the small-dollar fundraising infrastructure that these organizations can mobilize. For a member like Jared Golden, who already runs a lean operation in a rural district where door-to-door canvassing matters enormously, losing access to organized volunteer labor could be as damaging as facing a well-funded primary challenger. The threat is not just about one race — it is about whether progressive infrastructure will be available to Democratic incumbents who need it in November 2026.
What Happens Next in the 2026 Primary Season
The 2026 primary calendar will test whether the anti-war energy translates into actual votes. Historically, progressive primary challenges against incumbents generate significant media attention but often fall short at the ballot box. Incumbents have name recognition, institutional support, and the ability to outspend challengers.
But the Iran conflict has introduced a variable that did not exist in previous cycles: an active, unpopular military engagement that the president launched unilaterally. If even one or two of these primary challenges succeed — or come close enough to significantly wound the incumbent — it will reshape how Democratic members approach future national security votes. The next Congress will face ongoing questions about Iran, potential conflicts elsewhere, and defense spending. How the 2026 primaries play out will determine whether red-state Democrats continue to view hawkish votes as safe, or whether they start calculating that the base poses a greater threat than the general electorate.
Conclusion
The Iran war powers vote has crystallized a tension that has been building inside the Democratic Party for years. Members representing conservative-leaning districts have long assumed that breaking with the party on defense issues protected them in general elections. But with 89% of Democratic voters opposing the Iran strikes and progressive organizations mobilizing $64 million worth of primary challenges across 30 districts, that assumption is being tested in real time. The four Democrats who voted against the resolution — Golden, Cuellar, Landsman, and Vargas — along with members like Moskowitz and Gottheimer who wavered before switching, are now navigating a political environment where there may be no safe vote.
The outcome of these primaries will have consequences well beyond 2026. If progressive challengers succeed or come close, it will signal to future Democratic officeholders that the base’s opposition to unilateral military action is not something that can be safely ignored. If the incumbents hold comfortably, it will reinforce the centrist argument that voters care more about results than litmus tests. Either way, the Democratic Party is heading into its midterm elections divided on one of the most fundamental questions in American governance: who gets to decide when the country goes to war.
