The Sunlight Foundation has a don't-miss examination of the one-hundredth of the top one-percent who give nearly a quarter of all political contributions. Here's what Lee Drutman has to say about their research:
In the 2010 election cycle, 26,783 individuals (or slightly less than one in ten thousand Americans) each contributed more than $10,000 to federal political campaigns. Combined, these donors spent $774 million. That's 24.3% of the total from individuals to politicians, parties, PACs, and independent expenditure groups. Together, they would fill only two-thirds of the 41,222 seats at Nationals Park the baseball field two miles from the U.S. Capitol.

They tend to cluster in a limited number of metropolitan zip codes, especially in New York, Washington, Chicago, and Los Angeles.
