In Maine, former state lawmaker Troy Jackson has emerged as the front-runner to replace Graham Platner as the Democratic Party’s nominee to challenge Republican Senator Susan Collins in November’s midterm elections. Over the weekend, Jackson’s campaign got a boost when several rivals withdrew from the race; meanwhile, Jackson received broad support in county-level meetings of the Maine Democratic Party ahead of a nominating convention next Saturday. Troy Jackson is a progressive who narrowly lost the Maine Democratic gubernatorial primary. Graham Platner withdrew his nomination for Senate earlier this month after a former girlfriend accused him of rape.
