There are all kinds of web-based search tools to see who's giving how much to political candidates.
This is one I saw for the first time today. It's handy. My link is to a search of the 72202 ZIP code. It shows presidential campaign contributors and even maps where they live. Scroll right over to Edgehill Road and see who the swells are backing (mostly Clinton, save for McCainites Curt and Chucki Bradbury.) You can search by city, street, name, etc.
Noted: Red-lights king Jennings Osborne hedged his bets -- $2,000 to Hillary and $2,300 to Huckabee.
