The ongoing trade dispute with Canada dominates political discussion in the United States’ border states. Seven states that share a frontier with Canada are holding Senate elections on Tuesday. Candidates on both sides of the aisle are framing their campaigns around the impact of what they describe as “insane tariffs.” Voters are hearing arguments about how higher duties affect local economies and cross‑border trade. Party leaders are using the tariff debate to differentiate themselves and to rally support. The outcome of these races will likely influence how the federal government approaches the tariff issue.
