Out of curiosity, can anyone explain why Dakota County, Nebraska was so close? It does contain South Sioux City, but a suburb of an already slightly Republican city is generally more Republican than the entirety of Dakota County.
Sioux City is not that Republican, (only barely voted Bush), and it's "suburbs" aren't really suburbs in a traditional sense, but rather simply parts that should be part of the city but fall across state lines (much like North Mankato here, which is really just the part of Mankato that was settled on the other side of the river.) South Sioux City is no more affluent or any less working class than Sioux City.
Beyond that...what's to say? Only three other counties gave Bush under 60%: Saline (not sure why)
Was settled by Hungarian immigrants and always had a historical Democratic tradition much unlike the neighboring area.
Fun fact, my brother went to college in Nebraska for one semester. While driving down, they went through Cherry county (that huge county in the north right next to the pandhandle.) While passing through Valentine (county seat and only town in the county of any significant size whatsoever) there actually was a sign posted to say to get gas now, as there was no more gas stations for another 90 miles. Not only was this correct, but for a good part of that 90 mile drive, there was no radio stations, and they were unable to use a cell phone (no nearby towers)
Urgh. Talk about hell.
