Donald Trump recently announced a 50% tariff on approximately $20 billion worth of Canadian goods and opened a duty-free quota for some imported beef. Canada immediately retaliated with reciprocal tariffs, raising its counter-tariffs on U.S. steel and aluminum products to 50% and imposing new taxes on other U.S. goods. This round of trade actions, coming about 70 days before the November midterm elections, is putting pressure on the Republican Party's prospects of retaining a Senate majority. Media outlets point out that the tariffs directly impact key Senate battleground states such as Maine, Michigan, Ohio, and Alaska. The Democratic Senate candidate in Michigan claimed that the new round of Canadian tariffs would cost families in the state an additional $3,200 per year. According to a poll this month, 56% of U.S. adults list the cost of living as their top issue, and among Donald Trump voters who feel the cost of living has risen, 42% point the finger at tariffs.
