Republicans looking for an explanation after their brutal midterm losses have settled on a convenient culprit: President Donald Trump’s war against Iran. That diagnosis lets the party blame the disaster without fully confronting Trump, his record, or the ideology Republicans remain determined to protect.

Vice President JD Vance helped establish the party line in his election postmortem on X. His listed priorities were ending the war, focusing on the cost of living and inflation, putting America first, and changing the nation’s relationship with Israel.

Each priority intersected with Trump’s unnecessary and disastrous war against Iran. Vance then made his conclusion unmistakable: “The reason we lost is the war. The president himself said so last night.”

Other voices on the right quickly joined the chorus. “[T]he Iran war has dragged on too long,” Texas Sen. Ted Cruz said. “It should have been brief, decisive and over. It needs to end.”

Conservative writer Robby Soave reached a similar verdict, writing, “[T]hat broken promise, the Iran War, is clearly why Trump’s voters did not show up for him last night.” The explanation gives Republicans a straightforward story about their electoral collapse.

Fox News host Laura Ingraham said voters “want things to kind of calm down. And they hate war. And I mean hate war. Especially if it means that they have to pay more.”

The war certainly supplied voters with additional reasons to punish Republicans, especially through its effect on domestic prices. It may have helped transform Democratic victories from a wave into something closer to a tsunami.

But Trump’s approval ratings during his second term show that the Republican problem began well before the war. According to Silver Bulletin, Trump entered the term with a 51.6% approval rating, suggesting that many people were willing to give him another chance.

By Feb. 28, 2026, when the war began, Trump’s approval had already fallen to 42.0%. He had lost roughly 10 points before the first bombs fell, which makes blaming the entire midterm catastrophe on the war more than a little convenient.

Trump initially received a modest boost after the fighting started. His promises of a short and easy war appeared to buy him some time, and his approval rating rose slightly to 42.5% on March 4.

That reprieve did not last. By Election Day, Trump’s approval rating had dropped to 38.3%, leaving Republicans chained to an unpopular president whose numbers had been deteriorating for most of his second term.

The breakdown is especially damaging to the Republican excuse making. Trump’s approval fell 9.6 percentage points between his first day in office and the war’s beginning, followed by another 3.7 point decline through Election Day.

Most of Trump’s collapse therefore occurred before the Iran war began, while less than one third came afterward. Those final points still mattered because even a modest shift can determine close races and turn a defeat into a rout across multiple contests.

But Republicans were already heading toward serious trouble because of Trump’s performance and their refusal to hold him accountable. The president repeatedly showed little concern about lowering prices or improving people’s lives, declaring, “I don’t think about people’s financial situation” and “I don’t give a damn” about suffering caused by high gas prices.

Without the war, voters might have focused more heavily on Trump’s corruption, which was already a major concern. Democrats might not have won the Mississippi Senate race, which was expected to be officially called soon, and they might have been looking at roughly 250 House seats instead of around 260.

There is no way to know precisely what the election would have looked like without the war. What the approval numbers do show is that Trump had already cratered before it started, while Republican candidates and officials continued tying themselves to him.

The Iran war was undeniably a factor in the Republican rout, and it may have made the punishment considerably worse. But the party’s political predicament was already firmly in place before Trump managed to botch that crisis too.
