Democratic Maine Gov. Janet Mills is taking steps to run for Senate in 2026, sources tell AP
September 16, 2025
Democratic Maine Gov. Janet Mills is taking steps toward running for the U.S. Senate in 2026. That’s according to two sources who spoke to The Associated Press. Mills would add another big-name Democrat to the list of candidates expected to vie for key Republican-held seats. Democrats would still face a difficult path to regaining the majority in an election when they need to win a net of four seats. Most of the races on next year’s ballot in states Republican President Donald Trump won comfortably last year. But Mills has a record of winning statewide and would be running in a place where Democrat Kamala Harris defeated Trump in 2024. That could mean a blockbuster race with five-term Republican Sen. Susan Collins.
