Trump’s Canada trade war threatens GOP Senate races in Alaska, Maine, Michigan, Ohio

President Donald Trump's escalating trade war with Canada threatens Republican Senate campaigns in border states like Maine, Alaska, Michigan, and Ohio ahead of the midterm elections, as voters grow frustrated with economic fallout. Trump raised tariffs on $20 billion in Canadian imports after negotiations collapsed, with Canada planning retaliatory tariffs. Republican Senator Susan Collins of Maine called the move a mistake, citing harm to local industries like lobsters and lumber. The dispute creates a political trap for Republicans, who risk angering Trump by opposing him. Democrats are capitalizing on the issue, with groups like Majority Forward already targeting Alaska's Senator Dan Sullivan over tariff impacts.
