Tensions Rise in Maine's Democratic Senate Primary

The Democratic primary for the Maine Senate seat is heating up as Governor Janet Mills faces a significant challenge from Graham Platner, an oyster farmer and populist candidate. Recent polling indicates Platner holds a commanding lead over Mills, with a Z to A Research poll showing him at 58% compared to Mills' 38%. This primary is crucial as both candidates aim to unseat incumbent Republican Senator Susan Collins in the 2026 midterms, a race deemed highly competitive.

Polling data reveals a divided Democratic electorate. While the Z to A Research poll shows Platner with a 20-point advantage, other polls present a tighter race. For instance, a Maine People’s Research Center poll indicates Platner leads by only two points (41% to 39%), with nearly 20% of voters undecided. A SoCal Research Center poll even shows Mills ahead by five points. The varying results highlight the fluid dynamics of the primary race.

Mills' tenure as governor has been marked by a series of vetoes that have drawn ire from labor groups and progressive activists. She has blocked legislation aimed at enhancing workers' rights, including bills that would have allowed farmworkers to discuss pay without retaliation and measures to improve tenant protections. Critics argue that her actions favor corporate interests over those of working-class citizens, raising questions about her alignment with the Democratic base.

Mills' campaign has defended her record, emphasizing her commitment to social issues like reproductive rights and healthcare. However, her critics, including former Maine state representative Andy O’Brien, contend that her economic policies reflect a conservative stance that may alienate progressive voters.

• “lays clear what our theory is, which is that we are not going to defeat Susan Collins running the same exact kind of playbook that we’ve run in the past – which is an establishment politician supported by the power structures, supported by Washington DC, coming up to Maine and trying to run a kind of standard race … We are really trying to build a grassroots movement up here. We need to build power again for working people, both in Maine and nationally.” — Graham Platner
