Now my question... Did Buchanan specifically target North Dakota or is he born there or...? What led him to doing do so well there relatively speaking?
He was born and grew up in DC. He campaigned pretty much exclusively in Safe Bush states, and was able to take advantage of the Reform Party's matching funds. A campaign in North Dakota is pretty cheap.
I'm not sure North Dakota is so much a paleocon state as it is an isolationist one: Ron Paul got 21% in the caucus this year, one of his best performances in the entire country, and back in the day it was the home of Gerald Nye, one of the leaders of the America First Committee and a leading opponent of intervention in World War II.
