Maplight, a nonpartisan research organization that tracks money in politics, analyzed the geographic origin of super PAC contributions in a new report. They found that a disproportionate amount of the donations — totaling $510 million as of Sept. 30, 2012 — comes from just a few American cities.
The city generating the most money? Washington, D.C. — $71.6 million representing 14 percent of all super PAC donations — followed by Las Vegas ($48.6 million, 9.5 percent); New York City ($40.7 million, 7.9 percent); Houston ($36.4 million, 7 percent); and Dallas ($32 million, 6.2 percent) rounding out the top 5 spots.
