Washington, DC — March 19, 2026 — Mercury Analytics today released new survey findings examining how Americans are responding to U.S. military action involving Iran. The survey finds that 40% of Americans say they support U.S. military action, while 32% oppose it and 28% report mixed feelings.
Political Affiliation Shapes Public Opinion
- 71% of Republicans support military action, compared with 21% of Democrats

At the same time, 75% of Americans express sympathy or goodwill toward the Iranian people.
Independent Voters Show Elevated Concern and Lower Confidence
- More than 80% of Independents express concern that the conflict could expand into a broader regional war, including nearly half who are very concerned
- Nearly half of Independents also report concern about retaliation or security risks to the United States and its allies
Confidence in President Trump’s Strategy
- 82% of Republicans report being very or somewhat confident

“Americans are responding to a conflict unfolding in real time, with implications far beyond the region,” said Ron Howard, CEO of Mercury Analytics. “The data shows a public that is divided on the action itself but aligned in its concern about escalation, economic impact, potential terrorist threats in the United States, and broader global stability. The most important signal, however, is among Independent voters — where confidence is low, concern is high, and expectations of a prolonged conflict are widespread. This combination represents a clear risk zone for policymakers, as Independents are both less anchored and more decisive in shaping outcomes in the 2026 election cycle.”
About the Study
The findings are based on a nationally representative survey of 1,014 U.S. adults conducted by Mercury Analytics on March 11. The study used Mercury’s Qual at Scale methodology, combining traditional quantitative questions with deep qualitative IDI like probing of all participants, providing statistically robust insight into both the quantitative data and the qualitative perspectives of a national sample.
