I can’t access the county data on Leip’s site prior to 1960. According to that French website, Tilden got 100% of the vote in a whopping 22 counties in 4 states. Going by the colors, Roscommon and Mackinac (73%) and the defunct Isle Royale & Manitou counties were Tilden’s best in Michigan.
In 1884, again, the French website says Cleveland got 100% of the vote in 10 counties in 3 states, though it appears the defunct county of Manitou gave him the highest vote in the state. Curiously, Gen. Benjamin Franklin Butler got 100% on Isle Royale as the Greenbacker candidate, his highest in the nation.
In 1888, Cleveland got 100% in 12 counties in 4 states, but again, it appears Manitou was his best again in Michigan.
In 1892, Cleveland got 100% in 5 counties (3 in TX, 2 in LA), but once again, Manitou was his best in MI.
It was noteworthy that Manitou County, former site of a Mormon settlement on Beaver Island under a self-proclaimed “King”, was lawless and without an organized government from the time the Mormons were driven away after “King Strang’s” assassination in 1856 until it was formally dissolved in 1895. Strang managed to serve in the MI legislature prior to his murder, as a Democrat (of course).
