The upcoming primary elections in Michigan and Wisconsin carry significant implications for Canada, as the results could influence the balance of power in the U.S. House of Representatives and, consequently, trade policies such as the Canada-United States-Mexico Agreement (CUSMA).
Primary season is well underway in the United States, with 20 states having already held votes to nominate candidates for the November midterm elections. The House of Representatives plays a crucial role in U.S. foreign policy and trade, making these races particularly important for Ottawa.
Democrats need a net gain of three seats to win control of the House. Several races in northern states, especially Michigan and Wisconsin, could be pivotal. Erin Covey of The Cook Political Report highlights Michigan, Wisconsin, and Ohio as key states that will have the biggest impact on control of both the House and the Senate.
According to Covey, the political environment strongly favors Democrats this year. Midterms are typically a referendum on the party in power, and President Donald Trump's approval rating remains below 40%, particularly weak among Independents. Despite redistricting that gives Republicans a 10-seat buffer, Covey believes Democrats are still favored to win the House.
In Michigan, four districts are worth watching: the fourth, seventh, eighth, and tenth. The seventh is a toss-up, the eighth leans Democratic, and the fourth is competitive despite leaning Republican. The central battleground is the tenth district in the northern Detroit suburbs, a lean Republican seat being vacated by Congressman John James, who is running for governor.
The tenth district's proximity to Detroit and Canada makes it a focal point for trade issues. "This is a seat that is very central to the car manufacturing industry," Covey said. "Because of that, I think people there have a mixed view of tariffs." David Dulio, a politics professor at Oakland University, noted that this area was where opposition to the North American Free Trade Agreement (NAFTA) first emerged, and the debate over CUSMA remains relevant.
Democratic candidates Eric Chung, Tim Greimel, and Christina Hines are vying for their party's nomination, while Republicans Michael Bouchard, Steffan Demetropoulos, Justin Kirk, and Robert Lulgjuraj are competing for theirs. The outcome of these primaries will set the stage for a general election that could have lasting effects on Canada-U.S. relations.
