What is the closest Senate race in Kentucky history?

The Kentucky Senate election decided by the narrowest margin was in 1984, 0.41 points. Mitch McConnell beat Walter D. Huddleston, 644,990 to 639,721. The next closest were 1920 (0.56 points) and 1998 (0.59 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 Kentucky’s two Senate seats. Special elections to fill a vacancy appear on the Kentucky 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 Kentucky election with a popular margin to measure.

How this ranking is measured

U.S. Senate general elections in Kentucky, 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.
