In Michigan’s 3rd Congressional District Republican primary scheduled for August 4, 2026, traders see Ryan Cushman, a businessman and National Guard veteran, and Terri DeBoer, a longtime former West Michigan broadcaster, as the leading contenders in a closely matched contest. Limited name recognition for both candidates, absence of an incumbent, and the district’s mix of suburban and rural voters across Kent, Ottawa, and Muskegon counties have kept the race tight, with no decisive polling edge or major differentiator emerging yet. DeBoer holds a clear fundraising advantage and secured an early editorial endorsement from the Detroit News, while Cushman emphasizes his local business and military background. Upcoming candidate forums, additional endorsements from county parties or state legislators, further fundraising disclosures, or targeted advertising in the final weeks could shift momentum and create separation ahead of primary voting.
