Donald Trump’s tariffs on Canada are worsening economic pressures in Maine, damaging industries such as logging and fishing in a state with longstanding commercial and family ties to its northern neighbour. The resulting anger could affect next year’s Senate race, where Democrat Troy Jackson is challenging Republican Susan Collins in a closely fought contest.

Molly and Alex London closed their logging business after tariffs made replacement machinery parts unaffordable, amid already high costs and record diesel prices. Maine sends about 40% of its exports to Canada, and although the state generally leans Democratic, Collins has repeatedly won by presenting herself as an independent, locally rooted senator; polls currently show her neck-and-neck with Jackson.
