Most Americans believe recent U.S. military action against Iran has gone too far, and many are worried about affording gasoline, according to a new AP-NORC poll.

As the war launched by the U.S. and Israel continues in its fourth week, the survey from The Associated Press-NORC Center for Public Affairs Research indicates that while Donald Trump’s approval rating is holding steady, the conflict could be swiftly turning into a major political liability for his Republican administration.

While Trump is deploying more warships and troops to the Middle East, about 59% of Americans say U.S. military action in Iran has been excessive.

Meanwhile, 45% are “extremely” or “very” concerned about being able to afford gas in the next few months, up from 30% in an AP-NORC poll conducted shortly after Trump won reelection with promises that he would improve the economy and lower the cost of living.
