The one percent of the one percent
Sunlight Foundation reports on the one percent of the one percent:
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. When it comes to politics, they are The One Percent of the One Percent.
These high-monied donors wield extraordinary power, in that they serve as gatekeepers for the ideas that will be allowed in campaigns, and as a group they are highly ideological:
Unlike the other 99.99% of Americans who do not make these contributions, these elite donors have unique access. In a world of increasingly expensive campaigns, The One Percent of the One Percent effectively play the role of political gatekeepers. Prospective candidates need to be able to tap into these networks if they want to be taken seriously. And party leaders on both sides are keenly aware that more than 80% of party committee money now comes from these elite donors.
