Voters across the United States were loud and clear on Tuesday in their historic drubbing of Trumpism. The election was a decisive rejection of Trump’s war on Iran and its staggering costs at home. While savoring their victory and the historic opportunity to restore America’s constitutional order, the Democrats should take the anti-war message of the election to heart, because they suffered the same verdict two years ago, when voters rejected the Biden administration’s wars in Ukraine and Gaza. Last week Israeli voters rejected Netanyahu’s reckless wars, and European voters are also rejecting parties that prolong the Ukraine War. The message of voters is the same everywhere: diplomacy is safer, more effective, and trillions of dollars cheaper than war.
On election night Trump conceded to Fox News, “I think a part of it was Iran.” The next day Vice President JD Vance was far blunter, posting on X: “The reason we lost is the war. The president himself said so last night… everyone knows why we lost.” In the AP Voter Poll, about 60 percent of voters said the decision to use military force against Iran was wrong, and about 90 percent called the cost of living a crucial or major factor in their vote.
The war and the cost of living were of course utterly intertwined. Gasoline prices, around $2.80 per gallon before the war began on February 28, had risen by about 55 percent by mid-May and reached a monthly average of $4.43 in September. The 10-year Treasury yield climbed from below 4 percent before the war to above 5 percent in the autumn, and the Pentagon sought more than $200 billion in supplemental war funding. Every family with a mortgage, a car loan or a credit card balance suffered from the war.
Voters everywhere are sending the same message: peace through diplomacy.
The first duty of the new Congress is to restore its constitutional authority over war and its power of the purse to ensure that US forces are not sent back into combat in Iran or anywhere else on the whim of a president and the behest of domestic or foreign lobbies. Trump must of course refrain from restarting the war, which was never remotely necessary or justified. Remember that on February 28, the day the US and Israel launched the war, Oman’s foreign minister, who was mediating the U.S.-Iran talks, had said that a deal was within reach.
The Democrats should not imagine that the anti-war lesson applies only to Republicans. Kamala Harris lost in 2024 because voters held the Biden administration responsible for the costs of its own wars. The energy shock that followed the escalation of the Ukraine war in 2022 drove up inflation, and gasoline topped $5 per gallon for the first time in June 2022. Biden twice rejected negotiations that could have ended the conflict: in December 2021, when his administration refused to negotiate on NATO enlargement in response to Russia’s draft security treaty, and in April 2022, when the Istanbul talks were abandoned at the behest of the US and UK.
The Gaza genocide also cost the Democrats directly. Among Americans who voted for Joe Biden in 2020 but not for Harris in 2024, 29 percent named ending Israel’s violence in Gaza as the main factor in their decision, the most frequently cited issue. The party’s voters have moved far ahead of its leaders. A New York Times/Siena poll in May 2026 found that roughly three-quarters of Democratic voters oppose US military and economic assistance to Israel.
