In a significant shift in political sentiment ahead of the 2026 midterm elections, a YouGov poll has revealed that a majority of Americans are less likely to support candidates who advocate for the US-Israel war on Iran. The survey, released on Monday, shows that 44% of respondents are deterred by candidate support for the conflict, while only 13% are more inclined. This indicates that a candidate's backing of the war is over three times more likely to dissuade voters than attract them. Economics also play a crucial role in these decisions, with 56% of respondents prioritizing domestic price stability over achieving President Donald Trump's military objectives in Iran. The poll further indicates that Congress should have the final say on ending the war, with 53% of respondents favoring this stance. This development comes after the US and Israel jointly launched a war against Iran on February 28, with concerns arising over President Trump's decision to bypass congressional authorization for the conflict. The poll's findings suggest that Americans are looking to Congress to play a more assertive role in preventing reckless wars. The unpopular US-Israel war on Iran, which has resulted in thousands of casualties and surging prices, is expected to emerge as a key issue in future elections, particularly the 2028 presidential election. This shift in foreign policy attitudes may lead to increased scrutiny of candidates' positions on US support for Israel and potential intervention abroad.
