A Donald Trump campaign event in Michigan was scrapped last week because several Republicans were unsure about sharing a stage with him.

Trump’s team reportedly planned for him to campaign in western Michigan last week, but plans fell apart when Republican candidates and their teams debated whether to show up.

Three Republican sources familiar with the matter told POLITICO that several candidates initially didn’t know whether to attend and be seen with Trump. They were concerned about being associated with Trump’s US-Canada tariff war, which has hammered the state, along with high fuel prices amid the Iran war.

Trump officials ultimately scrapped the Western Michigan event and said he would visit the state later in the month.

Trump’s tariffs and the Iran war have become major liabilities in a state like Michigan.

Canada is Michigan’s top export market, buying $23.2 billion in goods last year, roughly 39% of all state exports, according to the Office of the U.S. Trade Representative. The state also conducts roughly $80 billion in annual trade with Ontario, according to the Michigan Chamber of Commerce.

The tariff dispute has put Michigan Republicans in a tough spot, especially Senate candidate Mike Rogers.

Rogers, who spent months defending Trump’s tariffs, including just last month saying that “Trump is right to put America first” by imposing duties on Canada, now calls for an end to tariffs.

“Here in Michigan, we know that Canada is not our enemy,” Rogers says in an ad earlier this month. “We need to end this tariff war now.”

Furthermore, Trump is a historically unpopular president, which is a drag on Republicans running in tight races.

“Trump is at historic lows right now, so if he comes to your district or state, it’s about getting the Republican base vote out there, and that can certainly help,” Ron Bonjean, a longtime GOP strategist, told POLITICO. “But it’s really important for the candidates not to be talking about Trump 24/7 on the campaign trail.”

“The war in Iran, I think, has become a real noose around the neck of Republican candidates because of the affordability crisis,” former Ohio Rep. Jim Renacci said.

A nonprofit he works with surveyed voters on whether GOP candidates should appear with Trump and found that “in most cases you do not want [Trump] standing near you, which is why I was a little bit surprised that Jon Husted has had two events with President Trump, because I do believe there’s a strong headwind in Ohio, and a big change from 2024.”
