Progressive political newcomer Graham Platner outraised both Democratic Gov. Janet Mills and Sen. Susan Collins in the first fundraising quarter in Maine’s key Senate race.
But Collins, seeking her sixth term, maintains a formidable cash advantage over both of her Democratic opponents that could give her a head start against whichever Democrat emerges from the June primary.
Platner raised $4.1 million in the first quarter, down from $4.6 million he had raised the prior quarter, while Mills brought in $2.6 million, down from $2.7 million in the final quarter of 2025, which had also included her campaign launch.
Collins brought in just over $3 million and had just over $10 million in the bank. She is also expected to be buoyed by a wave of outside money, with a super PAC supporting her, Pine Tree Results, reporting another $11.5 million cash on hand. Platner had $2.7 million in the bank, while Mills had just over $1 million.
Maine is one of national Democrats’ top targets as they seek to take back the Senate, with Collins the only Republican senator representing a seat won by Kamala Harris in 2024.
But it is one of the few battleground states where Democrats do not have a clear cash advantage. The comparatively lower fundraising totals for Platner and Mills compared to Democratic Senate candidates in states such as Ohio and North Carolina may reflect that some donors are still waiting on the sidelines to see which of the pair emerges to face Collins, while others are choosing sides.
Both Platner and Mills have faced challenges, albeit very different ones, in the primary. Mills, a two-term governor who entered the race with the backing of national Democrats, has trailed in recent public polling despite her near-universal name recognition. Platner, an oysterman and military veteran, quickly caught national attention and has drawn large crowds in the state. But he has been beset with a string of controversies involving old Reddit posts that began in mid-October, near the beginning of the previous fundraising quarter.
