Robert Charles holds the lead in the Maine Republican primary for governor, reflecting his consistent edge in polling and background as a former U.S. assistant secretary of state with broad name recognition among party voters. Recent straw polls show Ben Midgley narrowing the gap through strong business credentials and campaign momentum, though trader pricing continues to favor Charles ahead of the June 9 contest. Ranked-choice voting has prompted cross-endorsements among trailing candidates such as Midgley with David Jones and Robert Wessels with Jonathan Bush, potentially consolidating second preferences without altering frontrunner positioning. These alliances and Charles’s decision to skip recent debates have shaped the final weeks of campaigning, with market odds incorporating historical primary patterns and the absence of major late developments that could shift the outcome.
