TARIFF NEWS : MAINE SEN . SUSAN COLLINS FIGHTS BACKLASH

What happened: U.S. tariffs on Canada became a central issue in Maine's Senate race, where incumbent Republican Sen. Susan Collins faces Democrat Troy Jackson as midterm voters go to the polls. Key numbers: Maine imports $4.1 billion in goods from Canada yearly, including $2 billion in heating oil and $263 million in electricity from New Brunswick. Why it matters: Experts say no midterm outcome is a guaranteed win for Canada, since Trump uses presidential powers to set tariffs. One analyst said exempted tariffs could be reimposed after the midterms.
