The Vote That Split the Democratic Caucus
The House rejected a war powers resolution Thursday that would have forced Trump to seek congressional approval before continuing strikes on Iran, with the measure failing 212-219. Only two Republicans—Thomas Massie of Kentucky and Warren Davidson of Ohio—crossed party lines to support it. But the real story was on the Democratic side, where four members defected and a group of centrist hawks introduced their own competing resolution.
Reps. Josh Gottheimer (D-N.J.), Greg Landsman (D-Ohio), Jim Costa (D-Calif.), Jared Golden (D-Maine), Henry Cuellar (D-Texas), and Jimmy Panetta (D-Calif.) unveiled an alternative that would give Trump 30 days to end hostilities and allow "a troop presence in the region for defensive purposes." Gottheimer's office argued the Khanna-Massie measure "requires the immediate withdrawal of U.S. forces, even while Iran is actively targeting American troops" and would signal "retreat to our adversaries."
Markets Give It a 7% Shot
Prediction markets had priced this outcome with brutal accuracy. "7% chance Congress passes a war powers resolution this month," Polymarket posted as the vote approached. After classified briefings that Democrats derided as "bullsht"—Rep. Dave Min's word choice—the odds barely budged. "They're coming in and bullshting us just like they did with Venezuela," Min told Axios.
The briefings only hardened battle lines. Sen. Elizabeth Warren called the war "illegal" and "based on lies" after her classified session. Sen. Blumenthal warned, "I am more fearful than ever, after this briefing, that we may be putting boots on the ground." Meanwhile, Senate Majority Leader John Thune argued Trump has constitutional authority to conduct strikes beyond the 60-day War Powers Act window—a position that sailed through Wednesday's Senate vote, which rejected a similar resolution mainly along party lines.
Primary Threats From the Left
Progressive groups are now preparing to primary any Democrat who voted no. "Any Democrat voting against this resolution is really voting against the base of the party, and it will be a very politically perilous vote," a senior progressive House Democrat told Axios. Justice Democrats, MoveOn, the Progressive Change Campaign Committee, and OurRevolution are coordinating the effort. "If the filing deadline has passed, they'll do it in '28," the lawmaker added.
Justice Democrats spokesperson Usamah Andrabi was blunt: "Any Democrat that votes against war powers is supporting Trump's war on Iran and deserves to be primaried because all voters across the political spectrum are wholeheartedly against it." Polling backs that claim—several surveys found Trump's Iran operation broadly unpopular with the American public.
What Happens Next
The failed vote amounts to a congressional endorsement of Trump's military campaign, which has already cost six U.S. service members' lives and triggered Iranian missile counterattacks. Speaker Mike Johnson called the war powers push a "moral hazard" that would "empower our enemies." But even some Republicans are nervous. Rep. Tim Burchett warned MAGA voters to "stay concerned" about Iran becoming "another forever war." Sen. Rand Paul wrote that Americans "have been robbed of a public debate" on the conflict.
Trump now has a free hand to continue strikes without congressional approval—at least until political pressure builds enough to force another vote. With Polymarket traders giving future passage only a 6% chance and progressive groups mobilizing primary challenges, the Democratic split over Iran may prove more durable than any ceasefire.
