All the political donors in your city, mapped

In the US, the vast majority of political donations come from a small number of people. Last year Crowdpac, a new site that says it wants to make data on money in politics more accessible, created some fascinating "heat maps" of major cities and metro areas showing where all those donors live. They include all itemized donations — from both small donors and large ones — for all state and federal races since 2004. Some of the maps go down to a block by block level, showing blue dots for Democratic donors and red dots for conservative ones. Check out this profile by the Washington Post's Sebastian Payne for more on Crowdpac, and here are the maps:

1) New York City and its surroundings

2) Houston, block by block

3) Chicago and Milwaukee

4) Hollywood, block by block

5) The Bay Area

6) Downtown Washington, DC, block by block

7) The Beltway

8) Atlanta

9) South Florida

10) Boston
