Trump's trade and foreign policies strain his voter base ahead of Senate contests
Voters who backed Donald Trump are growing upset over his trade war and Iran strike, threatening Republican Senate hopes in key swing states.
A series of interviews across six pivotal states shows that a sizable share of Donald Trump’s base is dissatisfied with his aggressive trade measures targeting steel, dairy, appliances, automotive parts and farm equipment, as well as his independent military action against Iran that has rattled financial markets. Voters like Candace Oxley in Ohio say they regret supporting him because rising food and fuel costs outweigh any perceived benefits.
Republican figures such as Senator Susan Collins and Senate candidate Mike Rogers are publicly urging a de-escalation of the trade conflict to protect their electoral prospects. A poll conducted by one outlet and Siena University indicates that 19 percent of likely voters disapprove of the trade policy, though it omitted questions on the Canada dispute. The growing frustration is shaping the dynamics of Senate contests in Ohio, Maine, Michigan and New Hampshire, with some former Trump supporters leaning toward Democratic candidates like Sherrod Brown and Chris Pappas.
Why it matters
Trump's policies are eroding his coalition, potentially reshaping the balance of power in the U.S. Senate.
