Maine Gov. Mills will announce challenge to Sen. Collins in key 2026 Senate contest, AP sources say
Janet Mills, urged by Democratic leaders, aims to unseat Susan Collins in a key battleground where Democrats need four seats to retake Senate majority, officials say.
- Janet Mills, Maine's two-term Democratic governor, will run for the U.S. Senate seat held by Republican Susan Collins in the 2026 election, according to sources on Friday.
- Mills' decision follows encouragement from national Democratic leaders, who saw her as the top candidate to unseat Collins and gain a critical seat for their uphill quest for a Senate majority.
- Mills, who began her trailblazing legal career in Maine in the 1970s and later served as attorney general, joins several Democrats already campaigning, including oyster farmer Graham Platner.
- Senator Bernie Sanders publicly supported Platner as “a great working class candidate…who will defeat Susan Collins” and criticized party leaders for pushing Mills to run.
- The race in Maine draws attention as it is the only 2026 Senate contest where a Republican incumbent defends a seat in a state won last year by Democratic nominee Kamala Harris.
