Overview

  • Democrat Graham Platner reported $4.6 million raised in the fourth quarter of 2025, surpassing Gov. Janet Mills’ $2.7 million.
  • Sen. Susan Collins’ campaign said it brought in $2.2 million in Q4 and $10.4 million total through the end of 2025.
  • The Senate Leadership Fund announced an initial $42 million investment to support Collins, signaling major outside spending.
  • Mills, who entered the race in mid-October, said her totals show she is best positioned to defeat Collins and pushed back on age concerns, telling CNN, “I’m not Joe Biden… I’m healthy.”
  • Recent polling cited in new analysis is mixed, with some surveys showing Platner ahead and others favoring Mills, reflecting a competitive and unsettled primary.
