I posted this in another thread and I'll post it here as well because it's pretty damn interesting:
In Kidder county in 2000, Buchanan got over 9%. However if you compare the 2004 to 2000 results, the Bush numbers are practically the same despite Buchanan breaking 9% in 2000. This means that most likely a good chunk of the Buchanan vote went to Kerry, or possibly even a majority. If not, then there was a massive swing to Kerry from previous Bush supporters. Kerry even won two precincts in the county, something he couldn't even do in Bismarck, sadly. I'm willing to be this was all because of Iraq.
I'm too tired now but tommorow I'll type up a more detailed analysis of why I think this happened, why Burleigh sucks and it'll be interesting to see if this happened in any other rural counties across the country.
I doubt Kerry won Buchanan supporters. Perhaps a different group turned out than in 2000, or there was severe economic trouble.
Here in California, we had a lot of Boxer-Bush voters, which I can't figure out, so you never know.
