Overview
- Voters will choose party nominees on Tuesday, June 9, in contests for governor, the U.S. Senate, and both U.S. House seats with the Senate race drawing the most national attention.
- Incumbent Republican Sen. Susan Collins faces Democrat Graham Platner, a political newcomer who leads the Democratic field despite controversies over past posts, a covered tattoo and allegations reported by the press.
- Fundraising has nationalized the matchup with Federal Election Commission filings showing Platner has raised roughly $16.2 million and Collins about $10.5 million, and the Cook Political Report rates the race a toss‑up.
- Maine’s ranked‑choice voting could decide several crowded primaries by moving second and later choices to the top if no candidate wins a majority on the first count.
- Open and competitive statewide contests include a roughly dozen candidates for governor and a shuffled congressional map with Rep. Jared Golden not seeking reelection and former Gov. Paul LePage the lone Republican in the 2nd District primary.
