Democrats who have recently found renewed unity in opposing President Donald Trump now face a new test after joint American and Israeli strikes on Iran. The party had rallied around criticism of Trump’s immigration and economic policies and hoped to capitalize on momentum heading into the midterm elections. However, the military action and the killing of Iran’s supreme leader have exposed fresh disagreements, particularly over whether Congress should limit the president’s war powers.

While many Democrats support a resolution to restrain further military action, several lawmakers who strongly back Israel have broken with party leaders and oppose the measure. The divide reflects broader tensions within the party over its relationship with Israel, tensions that intensified during the war in Gaza and the 2024 presidential campaign. Progressive activists argue that voter sentiment is shifting, pointing to recent primary results and polling that suggest growing sympathy for Palestinians and skepticism toward Israeli government policies.

Early public opinion surveys indicate that a majority of Americans disapprove of the strikes and believe the president should seek congressional approval for additional military action. Opposition is strongest among Democrats and independents, while most Republicans support the decision. Rising economic concerns, including potential increases in gas prices, could further shape voter attitudes.

The political impact may become clearer in upcoming primary elections, where candidates are already clashing over the conflict and outside political spending tied to pro Israel groups. As the war unfolds, Democrats must balance internal divisions with their broader effort to present a unified front against Trump in a critical election year.
