Trump Canada Tariffs Challenge Republican Senate Candidates

President Donald Trump's escalating trade war with Canada is creating a significant political challenge for Republican candidates in several of the year's most closely watched Senate races. The dispute intensified after trade negotiations collapsed, leading the administration to impose new tariffs on roughly $20 billion in Canadian imports. Canada responded on Tuesday by announcing retaliatory tariffs on U.S. goods, with those measures scheduled to take effect September 8. The escalating standoff threatens to disrupt supply chains and raise consumer prices in key battleground states just weeks before voters decide control of the Senate in the November midterm elections.
