Americans for Prosperity is a free-market, free-trade, limited government advocacy group according to the non-partisan Factcheck.org. Much of this is due to its founder, David Koch. Koch, along with his brother, Charles, runs Koch Industries, the second-largest private company in the United States. According to Politico, the Koch brothers’ network planned to spend $889 million during the 2016 election cycle, double the amount the Republican National Committee spent in the 2012 presidential election cycle. The Kochs distribute money directly to candidates and through a network of super PACs and 501(c)(4)s. The Kochs' political philosophy tends to lean toward the libertarian, as do the causes and candidates they support.
involvement in federal and state elections:
Americans for Prosperity targets Democratic presidential candidates as well as Democrats in Senate and House races who vote against its free-market philosophy. The organization has run ads in tight races to boost Republican candidates, making the most of its knowledge of the FEC's "reporting windows" according to The Center for Responsive Politics. Americans for Prosperity has also been credited with helping to turn the Tea Party into a political force. In 2012, the group spent $33.5 million opposing incumbent Democratic presidential candidate Barack Obama. The group has not yet endorsed a candidate in the 2016 presidential campaign.
Wellspring Committee gave $1.65 million in 2008; the Center to Protect Patient Rights donated $13.8 million from 2009-2011, and Freedom Partners Chamber of Commerce donated $51.36 million from 2012-2014. According to The Washington Post and Mother Jones, all three groups have received money from the Koch donor network and distributing it to other like-minded conservative 501(c)4s or PACs.
