Derek Merrin's overwhelming trader consensus at 88.5% in the OH-09 Republican primary reflects his frontrunner status as the 2024 GOP nominee, where he won the primary and fell short by under 1% against incumbent Democrat Marcy Kaptur amid a now more Republican-leaning district post-redistricting. His eight years as a state representative, strong Q3 2025 fundraising exceeding $400,000, and superior name recognition position him ahead of challengers in a crowded field. Madison Sheahan's 6% share draws from her Trump-era ICE deputy director role but trails amid debate challenges and scrutiny; state Rep. Josh Williams at 3.8% touts local economic wins and recent top fundraising claims. With no public polls and the May 5 primary approaching, odds emphasize Merrin's path absent late shifts.
