Maine Governor Janet Mills has thrown her hat into the ring in what could be a hard-fought primary race for the right to challenge longtime Senator Susan Collins in next year’s midterm election.
The 77-year-old Democrat announced her candidacy in next year’s primary in a video highlighting the high-profile clash she had with President Donald Trump earlier this year over her state’s treatment of transgender children. Mills will have to defeat oyster farmer Graham Platner, a relative newcomer to Maine politics who launched an insurgent campaign in August with the backing of Vermont Senator Bernie Sanders.
