Traders view Nirav Shah as the frontrunner in Maine’s Democratic primary for governor, assigning him a 45 percent implied probability based on his prior statewide role as attorney general and established donor network. Troy Jackson sits at 27.5 percent, supported by his Senate president position and rural voter outreach. Hannah Pingree holds 14 percent with backing from her legislative leadership experience, while Shenna Bellows at 8.7 percent and Angus King III at 5.2 percent draw narrower progressive and independent-leaning support. No major developments have altered the field in recent weeks, leaving the contest open to shifts from upcoming endorsements, fundraising reports, and candidate debates before the June primary.
