What is the closest Senate race in Ohio history?

The Ohio Senate election decided by the narrowest margin was in 1964, 0.44 points. Stephen M. Young beat Robert Taft Jr., 1,923,608 to 1,906,781. The next closest were 1944 (0.60 points) and 1970 (2.2 points).

How is the margin measured?

As the gap in vote share between the first and second-place finishers, from the certified general-election count. It is not adjusted for recounts, runoffs or later court rulings; the figure is the result as certified.

Does this include special elections?

No. These are the regular general elections for Ohio’s two Senate seats. Special elections to fill a vacancy appear on the Ohio Senate hub, which lists every race including specials, and in a few states one of those is closer than anything here.

Why does the list start in 1914?

Because senators were chosen by state legislatures before the Seventeenth Amendment. 1914 is the first cycle of the popular-vote era for the Senate, so it is the first Ohio election with a popular margin to measure.

How this ranking is measured

U.S. Senate general elections in Ohio, ranked by the smallest gap in vote share between the top two finishers, 1914 to the present, closest 25 shown. Served from the senate_race_margin materialized view. Special elections are excluded, and so is any contest where the top two did not draw at least 1,000 votes between them or where the recorded winner was not the vote leader. The national list of the closest Senate races anywhere applies a 50,000-vote floor, which is why a small early race can appear here and not there.
