‘Reason we lost is the war’: Vance blames Iran conflict for midterm defeat

US Vice-President JD Vance has blamed the war with Iran for the Republican Party's defeat in the midterm elections, saying several voters who backed President Donald Trump in 2024 switched to the Democrats despite turning out to vote. His remarks came after Democrats won control of both chambers of Congress in Tuesday's elections, ending two years of Republican control.

In a post on X, Vance said, "The reason we lost is the war. The president himself said so last night." While acknowledging that the Republican campaign could have focused more strongly on economic issues, he rejected the suggestion that poor voter turnout alone explained the party's defeat.

One of the things the data analysts on our side obsessed over was "composition"—whether the electorate looked close enough to 2024 for Republicans to win. And despite polls that showed a Democrat blowout, the data kept on telling us the same story: in some states turnout was merely OK, in other states it was downright amazing, and in no state was it catastrophic. There was a genuine sense of optimism on our team: our people were showing up. So, I asked the smartest data guy I know, does that mean we're going to shock the world? "No," he told me. "We might do better than the polls suggest. But the data is telling us that a lot of Trump/Vance 2024 voters are pissed and planning to vote for the other guys. Our voters are turning out, but they may not vote for us." Well, that looks prophetic now. Our voters did show up. In Florida, for example, the electorate was 9 points more Republican than Democrat, just a couple points worse than 2024. Undoubtedly there were places we could have done better on turnout. But the main problem is not turnout. The main problem is that many people who voted for Trump/Vance in 2024 voted for Democrats in 2026. There will be a lot of infighting and arguing over what happened and why that is. One of the pollsters I really respect told me that our economic messaging wasn’t sharp enough down the stretch. I’m sure that’s true. But the real reason we lost is obvious to almost everyone. Another pollster—one of the smartest people I know in politics, told me yesterday we’d lose the generic ballot by 13 points. I felt negative going into Tuesday, but even I was shocked by this. In his polling, he saw that a lot of Trump 2024 voters were angry and planning to vote for Democrats. He asked those voters who had abandoned us what would cause them to come back on our team. The top four answers, accounting for nearly all of the responses were: 1) End the war 2) Focus on cost of living/inflation 3) Put America First 4) Change our relationship to Israel Our voters showed up. And the above four reasons are why many of them voted for Democrats. This is according to a pollster who nailed the results. While many spent Monday attacking Rachel Campos Duffy for calling for a diplomatic resolution to the conflict, it turns out her political advice was sound. (She’s also a great person.) In the next few months, there's going to be a lot of gaslighting. Expect to hear any number of establishment politicians say the solution to our woes is amnesty. I'm open to the idea that we should change enforcement—by focusing more on businesses that hire illegal labor, for instance. But anyone pushing amnesty is lying to you. The reason we lost is the war. The president himself said so last night. If you'd like to argue it was worth it, that losing the Senate for the next 6 years was worth it, then do so. Argue it was a worthwhile cost to pay. Agree or disagree, that's at least honest. But everyone knows why we lost. And any honest conversation about where we go from here must start there. I remain hopeful about our country. To the people who are pissed off and want to say, “I told you so”: you’re right, you did tell us so. Take that energy into electing Republicans who share your worldview. To the people who are just pissed at the results, you should be. Let’s take that anger and get back to the work of saving our country.

Donald Trump says Iran conflict contributed to election losses

Trump also acknowledged that the war with Iran had affected Republican support, although he stopped short of identifying it as the sole reason for the election setback. Speaking to The Wall Street Journal, he said, "Iran was a piece of it," while defending his decision to launch military action against Tehran.

"I did the right thing," Trump said. "I would have done it again," he said.

The conflict, launched by the United States and Israel against Iran in late February, has continued for more than eight months. During this period, rising energy prices and the cost of living have remained major concerns for American households, making them important issues in the election campaign.

Democrats win control of US House and Senate in midterm elections

The election results marked a major setback for Republicans, with Democrats securing majorities in both the House of Representatives and the Senate. Their victories included key Senate contests in Texas, Kansas and South Carolina, where Republican candidates had previously enjoyed strong support.

With all 435 House seats and 35 Senate seats contested on November 3, the results will reshape the balance of power in Washington. Republicans will lose control of Congress when the newly elected lawmakers take office in January, making it harder for Trump to push through legislation without support from Democrats.

JD Vance rejects calls for immigration amnesty after defeat

Vance also criticised Republican figures whom he expects to use the election setback to renew demands for an amnesty for undocumented immigrants. Instead, he suggested that immigration enforcement could place greater scrutiny on businesses employing workers without legal status.

However, he rejected the suggestion that immigration amnesty was the answer to the party's electoral problems, indicating that Republicans needed to pay closer attention to the concerns of their voters.

The Vice-President also defended television presenter Rachel Campos-Duffy, who had called for a diplomatic resolution to the Iran conflict. In a message directed at Republican voters who had warned the administration about the consequences of the war, Vance acknowledged their concerns and said, "you're right, you did tell us so."

His remarks underline the growing debate within the Republican Party over the political consequences of the Iran conflict and the need to regain the support of voters who helped Trump win the 2024 presidential election.
