Janet Mills drops out of Maine Senate race

Maine Gov. Janet Mills has dropped out of the state's U.S. Senate race, saying she does not have the financial resources to continue.

Multiple outlets reported the decision on April 30, including AP syndication and Maine Public. Mills' exit is a major shift in the contest to unseat Republican Sen. Susan Collins.

The move appears to clear the way for Graham Platner to become the leading Democratic contender in the race. Reporting said Mills' campaign had struggled to raise enough money to keep pace.

The decision came the same morning the news broke, making it one of the most consequential developments so far in Maine's 2026 Senate campaign.

What happens next will depend on whether Mills formally endorses another candidate and how quickly Democratic voters and party leaders consolidate around the remaining field.
