National Democrats see Mills as a strong challenger. The race intensifies as endorsements favor Mills, despite Sanders backing Platner.

Maine Governor Janet Mills officially entered the U.S. Senate race on Tuesday, joining a competitive field aiming to unseat Republican Senator Susan Collins. Mills, regarded as the establishment favorite, faces a significant primary challenge from progressive newcomer Graham Platner, who has already raised $3.25 million.

National Democrats have quickly rallied around Mills, highlighting her record as a seasoned election winner in Maine. On the endorsements front, Senator Catherine Cortez Masto has thrown her support behind Mills, setting a dynamic stage for the Democratic primaries.

This Senate race is seen as a critical pickup opportunity for Democrats in 2026. While Mills focuses on addressing economic issues, Collins, a formidable incumbent, remains a central figure in the political landscape. Vermont Senator Bernie Sanders has endorsed Platner, underscoring the primary’s high stakes and ideological divisions.
