A poll released on March 19 by IMEU Policy Project and Demand Progress, and conducted by Data For Progress, revealed that a majority of likely voters disapprove of President Trump’s strikes on Iran, favor congressional action to limit his military moves, and see the war as benefiting Israel more than America.

The survey of 1,215 likely voters indicated that voters are less inclined to back Republicans in the November midterms due to the war, while Democrats could gain an advantage by contrasting their stance against excessive support for Israel.

A Democratic congressional candidate in a general election who pledges to cut support for Israel to focus on domestic priorities gains a 15-point advantage over one who emphasizes prioritizing support for Israel.

A majority of voters oppose the war with Iran and consider it to favor Israel over the United States.

56% believe war against Iran benefits Israel more than it benefits America, while just 29% say America benefits more.

53% of voters disapprove of Trump’s strikes against Iran, while 43% approve, contributing to polls showing majority disapproval for this war—the lowest initial approval for a US war in decades.

51% support Congress passing a war powers resolution to curb Trump’s military actions against Iran, while 44% oppose such a resolution.

Voters are less likely to back Republicans in November because of the war with Iran, with younger Republicans increasingly distancing themselves from party leadership.

43% of voters say they are less likely to support Republicans in 2026 as a result of Trump’s war, while 31% say they are more likely.

Republican voters are roughly split in a primary between a candidate who would reduce support for Israel and one who prioritizes it, with sharp age-based divisions.

61% of Republicans under age 45 would prefer a candidate who would reduce support for Israel, while 56% of Republicans over age 45 would prefer a candidate who prioritizes support for Israel.

In a general election matchup between Republicans and Democrats holding identical views on prioritizing support for Israel, Republicans hold an edge.

Democrats who pivot to pledging reduced support for Israel secure double-digit victories.

A plurality of voters believe Israel exerts excessive influence over US foreign policy.

43% of voters say Israel has too much influence over US foreign policy, while 41% say the right amount and just 5% say too little.

59% of Democrats and 25% of Republicans say Israel has too much influence—which rises to 32% among Republicans under age 45.

Separately, a poll released in December by IMEU Policy Project and conducted by YouGov found that a majority of Republicans under age 45 wanted to reduce taxpayer-funded support to Israel, and that Democrats who backed restricting support to Israel could attract significant Republican crossover votes.

A September 2025 YouGov poll released by IMEU Policy Project and Gen-Z For Change also showed Democratic voters were far more likely to abstain from a general election if a Democrat prioritizing support for Israel appeared on the ballot.
