Recent polls of likely Republican primary voters, including a late March survey showing U.S. Rep. John James at 23% and self-funding businessman Perry Johnson at 20%, underscore the tight trader consensus with James holding a slim edge at 40% implied probability over Johnson's 37%. James benefits from name recognition from prior congressional runs and strong traditional GOP support, while Johnson gains traction among MAGA voters through personal funding, Macomb County strength, and a Saginaw straw poll win. Early April mutual attacks over fundraising texts highlight escalating competition, but no clear separation yet. Endorsements, debate performances, and pre-August 4 primary fundraising reports could tip the balance in this fragmented field.
