Nancy Mace Just Voted to Rein In Trump's Iran War: One of 7 Republicans, Six Months After She Vowed to 'Finish the Job'
On the night of September 15, 2026, the House voted 220 to 204 for the third time to rein in President Trump's war with Iran. Seven Republicans crossed the aisle, and Nancy Mace was one of them. She was also one of three who did it for the first time. Six months earlier, on March 5, 2026, Mace had voted NO on a materially identical war powers resolution and declared: 'This is not the time for Congress to tie the hands of our Commander-in-Chief. We must finish the job.' This dispatch records the reversal, the roll call, and the breaking-news footage, captioned to show Mace among the seven.
Reporting relied on: The Associated Press (via U.S. News & World Report), CNN, CBS News, The New Republic, Jewish Insider, and the Daily Caller for the September 15 vote; Rep. Mace's own House statement of March 5, 2026 for her prior position; and the breaking-news floor footage aired by 6abc Philadelphia (WPVI/ABC) and WPLG Local 10 over the C-SPAN feed. Every figure below is drawn from those sources and the official roll call. This dispatch is about Nancy Mace's public voting record and her own public statements.
Late on the night of September 15, 2026, the U.S. House voted 220 to 204 to rein in President Trump's war with Iran. It was the third time the chamber has passed such a war powers resolution, and this time seven Republicans crossed the aisle to join every voting Democrat.
Nancy Mace was one of the seven. She was also one of three Republicans who did it for the first time.
Watch: the vote, captioned
The breaking-news footage from 6abc Philadelphia (WPVI/ABC), carried over the C-SPAN House floor feed, shows the official tally board: H. Con. Res. 93, Republicans 7 yea and 203 nay, a 220 to 204 total. We captioned it to show where Mace stands in that count.
The vertical cut, for phones:
The seven
The seven Republicans who voted yea on the war powers resolution:
- Nancy Mace (South Carolina), first time
- Mariannette Miller-Meeks (Iowa), first time
- Zach Nunn (Iowa), first time
- Tom Barrett (Michigan)
- Warren Davidson (Ohio)
- Brian Fitzpatrick (Pennsylvania)
- Thomas Massie (Kentucky)
Four of them (Barrett, Davidson, Fitzpatrick, and Massie) had supported earlier versions of the resolution. Mace, Miller-Meeks, and Nunn had not. Their votes are why the Republican defection count rose from four to seven.
The flip: what Mace said six months ago
This is the reversal. On March 5, 2026, the House took up a materially identical war powers resolution, and Mace voted NO. Her office then issued a statement that left no daylight between her and the president:
"We voted NO on the War Powers resolution, without hesitation. This resolution would have ordered President Trump to stand down military operations against Iran's terrorist regime mid-operation... President Trump is doing what needs to be done. Forcing a halt mid-operation doesn't protect Americans, it empowers our enemies, undermines our military, and puts American lives at risk. This is not the time for Congress to tie the hands of our Commander-in-Chief. We must finish the job."
Six months later, she voted to tie those hands.
The context she is voting from
Mace is a lame duck. She did not seek re-election to her South Carolina House seat because she ran for governor instead, and on June 9, 2026 she finished fifth in the Republican gubernatorial primary with roughly 12 percent of the vote. The Associated Press now describes her as "retiring Rep. Nancy Mace." She will leave Congress in January 2027. The other two first-time defectors, Nunn and Miller-Meeks, sit in battleground districts and face voters again in 2026. Mace does not.
What the vote does, and does not, do
H. Con. Res. 93 is a concurrent resolution. It expresses the sense of Congress; it does not carry the force of law the way a joint resolution would. None of the three House-passed resolutions has reached the president's desk, and the AP notes that Trump "would almost certainly veto the measure" if one did. The vote is a rebuke and a marker of growing Republican discontent with a war that has now dragged on for months. It is not, by itself, a stand-down order.
That distinction matters, and it cuts against the loudest version of this story. What changed on September 15 was not the war. What changed was Nancy Mace's vote.
In her own words, then and now
- March 5, 2026: "We must finish the job."
- September 15, 2026: one of 7 Republicans voting 220 to 204 to end it.

On September 1, 2026, Nancy Mace appeared on CNN's The Situation Room and told Wolf Blitzer she was ready to vote for the War Powers Act: 'The grace period is over.'

September 15, 2026 · Dispatch'It Could Be by Firearm, It Could Be Electric Chair. I Don't Really Care': After the Lindsay Clancy Mistrial, Mace Returned to TMZ and Demanded a Public Execution in a State That Abolished Capital Punishment in 1984
On September 14, 2026, ten days after the Lindsay Clancy mistrial, Rep. Nancy Mace stopped a TMZ camera in Washington and escalated. Where her September 2 appearance falsely predicted Clancy would 'walk free,' this one demanded a public execution by firearm or electric chair, in Massachusetts, a state that abolished capital punishment in 1984 and has not executed anyone since 1947. The case is not over: a retrial decision is pending at a September 29 status hearing, and Clancy remains held in a state psychiatric hospital. President Trump, asked about the mistrial, called it 'horrible' but predicted 'mental institution or jail or something', accurately describing what Massachusetts law provides and implicitly contradicting Mace's 'walk free' claim from two weeks earlier. This dispatch records Mace's five new verbatim quotes, the Trump contrast, and the law as it actually stands.
September 3, 2026 · Dispatch'She's Going to Walk Free Because of This Pink Mob': Nancy Mace's Lindsay Clancy TMZ Hit Manufactured a Racial Controversy Around Two Claims That Are Provably Wrong, One of Them About the Law
On September 2, 2026, with the Lindsay Clancy jury deadlocked into its fifth day, Rep. Nancy Mace stopped to talk to TMZ in Washington and turned the Massachusetts murder trial into a racial controversy. She told the camera the 'pink mob' of women supporting Clancy would abandon her 'if she were Black,' that 'the left is inherently racist,' and that Clancy is 'going to walk free because of this pink mob.' The two claims driving the segment do not survive the facts. Mace named no case to support the racial charge, and 'walk free' is not what the law provides: Clancy's defense is asking the jury for a verdict of not guilty by reason of insanity, which in Massachusetts means indefinite commitment to a locked psychiatric hospital, not release; a deadlocked jury means a retrial, not freedom; and Clancy has been held in a state psychiatric hospital the entire time. This is Maceopedia's record of the interview, every quote verbatim and attributed.

On her Thursday, August 27, 2026 'Get Maced' live stream, Nancy Mace devoted a segment she titled 'the face of evil' to the murder trial of Lindsay Clancy, the Massachusetts mother whose jury had just begun deliberating. Mace told her viewers, 'I really want Lindsay Clancy to get the death penalty, and I'd prefer it to be public,' having acknowledged in the same breath that Massachusetts has no death penalty, where the maximum sentence is life without parole and no verdict had been reached. She also disclosed her own postpartum experience to draw a line against Clancy ('the only difference is I didn't murder my children'), mocked the defense attorney's closing ('I don't know any darn good moms who murder all three of their children'), and built the rest of the hour around a thesis about the gap between who people claim to be and who they are: Hillary Clinton in the Hamptons, Michigan Senate nominee Abdul El-Sayed and his physician title, and a closing tribute to Dolly Parton. This is Maceopedia's review of the broadcast, every quote verbatim from her own stream.
August 26, 2026 · DispatchAmateur Hour: Nancy Mace's First 'Get Maced' Live Stream Was Muted at the Open, Out of Focus in the Middle, and Watched Live by Fewer Than 1,000 People
On the night of the August 25, 2026 South Carolina runoff for the late Lindsey Graham's Senate seat, Nancy Mace went live on her personal @NancyRMace YouTube channel for the first time ever: a 45-minute, one-camera runoff-watch show she opened by admitting the microphone had been muted the whole time she'd been talking, narrated her own camera going out of focus, and paused near the 40-minute mark to go get a glass of water. Fewer than 1,000 people watched it live. The content whiplashed too: she spent the front half prosecuting the appointment of Graham's sister Darlene ('It's not an heirloom... it could be Donald Duck, it could be Mickey Mouse') and the back half, once Darlene won and Mace's own pick Ralph Norman lost, congratulating 'Senator Graham' and pledging to help her. Her staff prompted her on air to remind viewers to subscribe. This is Maceopedia's television-critic review of the broadcast, with the full edit of the night's quotes and snafus.
September 24, 2026 · DispatchMace Hits Mehdi Hasan With His Own Deleted "Make American Planes Crash Again" Post on Piers Morgan
During a heated September 17, 2026 Piers Morgan Uncensored debate over radical Islam, Rep. Nancy Mace (R-SC) turned the tables on journalist Mehdi Hasan by throwing one of his own deleted posts back at him. Mace reminded Hasan that after a fatal U.S. plane crash he had written "Make American Planes Crash Again," calling it "disgusting," "hypocritical," and "a bad joke about Donald Trump crashing planes." Hasan posted the line on February 16, 2025 as a jab at Trump over aviation safety, then deleted it the next day, calling it poorly worded. This is the same on-air clash in which Hasan called Mace "a racist bigot."
