Will the Senate hold an eighth Iran war powers vote next week? Slowly but surely R's breaking ranks.
66% of users predicted YES — the community got this one right. 32 predictions cast.
The Senate on May 20, 2026, voted 50-47 to advance a war powers resolution limiting President Trump's authority to conduct military operations against Iran, marking the eighth time Democrats brought such a measure to the floor — and the first time the procedural vote succeeded. Four Republicans — Sens. Susan Collins of Maine, Lisa Murkowski of Alaska, Rand Paul of Kentucky, and Bill Cassidy of Louisiana — joined most Democrats in favor, while Sen. John Fetterman of Pennsylvania was the lone Democrat in opposition. Three Republican senators did not vote, effectively tipping the outcome.
The breakthrough came as bipartisan skepticism of an open-ended Iran conflict deepened in Congress. The 50-47 tally discharges the resolution from committee and allows limited debate and a final floor vote, after which the measure would need to clear the House.
Even if the resolution passes both chambers, President Trump has indicated he would veto it, leaving the measure with little realistic prospect of becoming law. Proponents framed the vote as a congressional rebuke of executive war-making power; critics argued it risks undermining U.S. leverage in ongoing Iran negotiations. The Predict Six community predicted YES at 66%, correctly anticipating the vote's success.
