Huffington Post now has a page called HuffPost Fundrace that makes it easy to search the public records that campaigns and PACs filed with the Federal Election Commission for all their individual contributors who gave at least $200 - by city, zip code, names or employers. (Unfortunately, you can't search on more than one factor at a time, so you can't ask for all the employers in Olympia,  for example.) You can see something about how much money Olympia puts into national campaigns, who in your zip code gave over $200 to anybody (and how much), who gave to Republicans and who gave to Democrats, and whether any of your friends or local political activists really put their money where their mouths have been.

In the current election cycle (from just after the November 2010 election to the third quarter of 2011, which is the most recent data on the site) it says people from my zip code, 98501, have contributed $90,922 in national elections. The $388,000 total for "Olympia" so far is very slightly misleading, because "Cities named Olympia" is what you can search for, and that includes Olympia Kentucky. (Olympia Kentucky is a pretty insignificant contributor to national politics, though - Google Maps shows it with seven streets, counting Highway 39.) Interestingly, almost all of the big contributors from our Olympia are people I never heard of...

To my surprise, almost none of people I know and looked up are shown as giving $200 or more to anybody either... (Of course, it might be that they make a lot of smaller contributions - though if you do that on line, through some organization like ActBlue that handles contributions for a lot of campaigns, all your donations show up as going to Act Blue, and if you gave $50 to four campaigns that way you'd be listed.)
