Janet Mills Heads Into First Senate Debate as Underdog
Maine Gov. Janet Mills is running for the Democratic nomination for U.S. Senate and enters the first debate next week as the underdog. She has decades of experience in office and the backing of the party establishment, but she is still facing a primary fight that will now move from campaign stops to a public debate stage.
Janet Mills In South Portland
Mills talked to reporters on Friday, April 17, 2026, in South Portland, Maine, as the race continued to sharpen around her Senate bid. She is seeking to win the Democratic nomination, and the debate next week will give voters their first direct look at how she handles the pressure of a race in which she has been described as the underdog.
Party Backing For Mills
The governor enters that debate with a record that stretches across decades in office, a point that gives her campaign a different profile from a challenger trying to build name recognition. The article describes her as having the backing of the party establishment, which places her in the unusual position of being the favored figure inside the party while still trailing in the primary narrative.
That split leaves Maine Democratic voters with a simple test: whether long experience and institutional support are enough to outweigh the candidate who is currently seen as the underdog. For Mills, the debate is the first chance to answer that in front of voters rather than through campaign messaging alone.
Graham Platner Town Halls
Graham Platner, another Democratic Maine Senate candidate, has already been on the trail in public settings. He acknowledged the large crowd at his town hall on September 25, 2025, at Bunker Brewing in Portland, Maine, and he spoke at a town hall in Ogunquit, Maine, on October 22, 2025.
Those appearances give the race a clear contrast heading into the debate next week: Mills arrives with the governor's office and establishment support, while Platner has been drawing crowds at town halls. The first debate will put both campaigns in the same frame, with Maine Democrats now able to compare them directly instead of through separate events.
