Other weird Nader result: Dawes Co, NE: 5.85%
Also, Obama did unusually well for western Nebraska in Dawes County and Box Butte County right south of there; over 30% in both. Why?
Chadron State College (Dawes) and Carhenge
(Box Butte). Actually, I'm not sure about Box Butte.
Edited to add: Box Butte County, along with Dawes, is one of a handful of Western Nebraska counties that has an actual town of any size. Obama also cracked 30% in Scotts Bluff County, which is another.
