Kevin is concerned with the privacy issues herein, but this shit is public record, as it should be.
FundRace 2004 allows you to search by zip code, address, or name for who's given what and how much to which campaign. I live near a lot of Deaniacs and a former city council member that I voted against gave money to Kerry. My old zip code features a lot of Bush supporters, but they're in the part that isn't heavilty populated by students. Which is where I lived. And there are very few donations to anyone from that part.
