At Campaign Donors : Fundrace 2008, one can use a search tool to look up campaign donors by zip code, city, last name, occupation, or employer.
I came across the site by accident while doing a search on a company name. The site revealed that the president of the company had made a campaign contribution to George W. Bush in 2004. I tried a search on my zip code and the site returned a list of people in my zip code who had made contributions to either the Democratic or Republican party and the amount donated.
The site states the following:
All calculations are based on public records filed with the FEC of contributions by all individuals totaling more than $200 (and some totaling less than $200) to a single Republican or Democratic presidential campaign or national committee for the 2004 and 2008 election cycles.
FundRace is updated according to the reporting schedule set by the FEC. Public contribution data is geocoded using public U.S. Census Bureau data. Dynamic maps are powered by Google Maps.
