Two Republicans in competitive Senate races—Iowa’s Ashley Hinson and Michigan’s Mike Rogers—called Monday for a swift end to the nearly seven-month Iran war, citing fuel costs, after previously backing President Trump’s authority to strike Tehran.

Hinson, a sitting House member who voted as recently as last week against measures curbing Trump’s war powers, wrote that Iowans “shouldn’t have to foot the bill at the pump or the checkout line” and urged suspending gasoline taxes, pausing diesel exports, and bringing the war to a “successful and immediate end.” Rogers, facing Democrat Abdul El-Sayed, released an ad from a grocery store saying the war “needs to end and end quickly” so energy costs can fall, while also seeking gas-tax relief and a temporary halt on U.S. diesel exports. Diesel prices carry special weight in Iowa’s farm economy.

The shift lands as a Reuters/Ipsos poll put Trump’s approval at a career-low 32%, with Americans souring on both the economy and the war ahead of November midterms that will decide narrow Republican majorities. Last week Iowa Representatives Zach Nunn and Mariannette Miller-Meeks reversed course and joined Democrats to limit Trump’s Iran war powers. Democrats cast the Senate candidates’ new tone as election-year repositioning: El-Sayed said Rogers flipped because gas hit $5 a gallon and diesel hit records; Hinson’s opponent Josh Turek noted she had chances to vote to end the war and did not.

Agreement in the coverage is that Hinson and Rogers are newly urging a quick end after earlier support for presidential war authority. Conflict is over motive and consistency—campaign necessity and pocketbook politics versus prior votes and statements—and over how far congressional Republicans will go in constraining a war Trump still defends at the United Nations.
