Exit poll findings released after the vote offer support for his claims, particularly on the war, while reactions from Republican lawmakers have added to the debate. US Vice President JD Vance blamed the Iran war and America’s relationship with Israel for the Republican Party’s losses in the 2026 midterm elections .
In a post on X on Wednesday, Vance said many people who voted for Trump in 2024 switched to Democrats in 2026. Democrats won control of both the House and Senate in Tuesday’s elections, dealing a major setback to President Donald Trump and his party. “The reason we lost is the war.
Citing a pollster, he listed four issues that could bring those voters back to the Republican side: ending the Iran war, addressing the cost of living and inflation, putting America First, and changing the US relationship with Israel.
The president himself said so last night,” Vance wrote.
The voter data offers support for Vance’s argument on Iran. Former Rep. 34% of voters said the war was a crucial factor in their decision, according to ABC News’ voter poll . The poll also found that 62% of voters believed the US made the wrong decision by using military force against Iran. Marjorie Taylor Greene also responded, saying the four issues listed by Vance were part of the Republicans’ 2024 campaign promises.
“You should have listened to me and Tucker and others who told you early,” she wrote, accusing the party of failing to deliver on its promises.
