Incumbent-like favorite Sherrod Brown commands 98% trader consensus for the Ohio Democratic U.S. Senate primary on May 5, driven by his three prior terms, unmatched name recognition, and dominant fundraising as Democrats' top recruit for the special election vacancy left by JD Vance's vice presidency. Post-February filing deadline, minor challengers Allison Russo, Greg Landsman, and Tim Ryan show no polling traction or momentum, with party endorsements and resources consolidating behind Brown despite his 2024 general election defeat. Recent general election polls pit him closely against Republican appointee Jon Husted, but primary odds reflect negligible upset risk absent a late scandal, health issue, or surprise endorsement shift in the final weeks.
