Who is forecasted today to win the Ohio Senate race?
Updated Monday, October 26, 2026 · 8 days to Election Day · VotePredictor
Sherrod Brown is favored. The VotePredictor forecast gives Brown a 75% chance of beating Jon Husted, with a predicted margin of Brown +2.2. That is a Lean D race: Brown wins about three times in four, and Husted in the other 25%.
What the forecast is built on
The forecast starts from the 22 public polls in the forecast window, whose plain average is Brown +3.5. Each poll is corrected for its voter screen and its pollster's measured house effect first (the “Adjusted” column below).
- The polls, weighted and corrected, read Brown +2.6.
- The fundamentals (the state's presidential lean, incumbency, the last result and the national environment) read Husted +1.5.
- The published forecast blends the two, mostly on the polls, at Brown +2.2.
Misses of a few points are common, so a 2.2-point lead is a 75% chance and not a lock.
