What is the biggest landslide in a South Dakota governor’s race?

The widest margin in a South Dakota gubernatorial general election came in 2014, 45.0 points. Dennis Daugaard beat Susan Wismer, 195,477 to 70,549. Next are 1904 (43.6 points) and 1982 (41.8 points).

Why do some huge wins not appear?

A blowout only counts here when somebody real finished second, which means at least 5% of the vote. Without that rule the list fills with uncontested races and with contests where the record is simply missing the major opponent, both of which show the winner near 100%.

Does this include recalls and special elections?

No, only regular general elections for governor. The South Dakota governor hub lists every race including specials and recalls.

How this ranking is measured

Gubernatorial general elections in South Dakota, ranked by the largest gap in vote share between the top two finishers, widest 25 shown. Served from the governor_race_margin materialized view. A qualifying race needs a genuine second-place finisher with at least 5% of the vote, and at least 1,000 votes between the top two. Recalls and special elections are excluded; the state hub lists those. The national list applies a 50,000-vote floor, so an early race can appear here and not there.
