Look up local donors here: http://www.fundrace.org/ (Use the neighbor search.) If you find a local businessman who supported Bush to the max, find another local source for those goods. I personally know a woman who spends hundreds of dollars a month on prescription drugs. She found out, on this site, that her pharmacist had donated the maximum amount to Bush and the GOP. She has transferred all of those prescriptions to another pharmacy, and she told him WHY.

Another excellent resource is "Open Secrets". They keep track of all of the money in US elections on every level, and there's a LOT of it. Slip them a few bucks if you can afford it. The site may seem daunting at first, but it's easy to use once you get the hang of it.
