Vance blames Iran war for Republican midterm rout, saying 'the reason we lost is the war'
US Vice President JD Vance has said the war in Iran cost Republicans the midterm elections, pointing to voters who backed Donald Trump in 2024 but switched to Democrats, while Trump called the claim 'largely true' but said he would do it again.
US Vice President JD Vance has blamed the war in Iran for the Republican Party's crushing defeat in the midterm elections, in the bluntest public break yet from a vice president widely seen as a contender for the 2028 presidential nomination.
In a lengthy post on X on Wednesday, Vance wrote: 'The reason we lost is the war. The president himself said so last night.' He was referring to President Donald Trump, who had told interviewers on election night that the Iran war was 'part of it' in explaining the Republican losses.
Vance said a pollster he respected had told him that many people who voted for Trump and himself in 2024 were angry and planning to vote for Democrats. According to Vance, the top four answers from those voters, accounting for nearly all responses, were: end the war, focus on the cost of living and inflation, put America first, and change the relationship with Israel.
He then issued a direct challenge to supporters of the war inside his own party. 'If you'd like to argue it was worth it, that losing the Senate for the next six years was worth it, then do so,' he wrote. 'Agree or disagree, that's at least an honest argument.' The post, running to 618 words, was his first public post-mortem on an election night that saw Democrats take control of both houses of Congress.
Trump responded later on Wednesday while touring the White House ballroom construction site. Asked whether he agreed with Vance, he said: 'I think it's largely true because it drove the gasoline up a little bit short term.' But he immediately defended the war itself, adding: 'If I had to do it again, I'd have to do it again. Because long term, it's the only answer. You can't let Iran have a nuclear weapon.'
The president also made clear he saw no breach with his deputy. A Trump aide told the New York Post that the president had been briefed beforehand on Vance's statement and had no issues with it, and Trump himself noted that he had known Vance was sceptical about the war when he went in, describing him in March as 'philosophically a little bit different' and 'maybe less enthusiastic' about going to war.
That scepticism has a long paper trail. During the 2024 presidential campaign, Vance said the US interest was 'very much in not going to war with Iran', and he was reportedly doubtful behind the scenes when Trump and Israel launched the war in late February 2026. His Wednesday post is therefore the closest he has come to criticising the president's defining foreign policy decision while serving as his second-in-command.
The political context is stark. Democrats trounced Republicans in the midterms, securing control of Congress in what Trump himself acknowledged was a major rebuke, and the result has already begun reshaping policy: Trump announced on Tuesday that Washington would end about $4 billion in annual aid to Israel by the end of the year, a move reported as a recognition of the political cost of the war and of growing voter scepticism about continued military assistance.
Vance's intervention also highlights a debate now running through the Republican Party about the cost of military intervention in the Middle East. The vice president framed the election as a verdict not only on the war but on the cost of living, arguing that voters who switched sides wanted the administration to end the conflict, tackle inflation and restore an 'America First' focus.
What happens next will test whether Vance's candour helps or hurts him. By naming the war as the cause of defeat while stopping short of condemning the president, he has positioned himself as the voice of the voters who abandoned the party, without openly breaking with Trump. Whether that balancing act survives the coming fight over the Democrats' new congressional majority, and over the future of the Iran war itself, will shape the Republican succession long before any 2028 campaign formally begins.
