A little-known, billionaire-funded organization, called Americans for Prosperity (AFP), has tilted American politics to the right. [It] is at the center of the political network created and directed by the billionaire conservative industrialists, Charles and David Koch. AFP has quietly pushed behind the scenes for many of the most important conservative victories across the nation, including the anti-union bills that passed in former union strongholds such as Wisconsin, Michigan, and Ohio. AFP's laser-like focus on anti-union legislation ... reflects strategic calculations. AFP has recognized that to make lasting change in US politics, the Koch network would need to permanently weaken the organizations that support liberal candidates and causes - and above all, the labor movement. In constructing AFP, the Kochs have created a vehicle that is perfectly positioned to reshape American politics. AFP focuses on both elections and policy battles at all levels of government. Its activities are mostly centrally directed. And even though grassroots participants do not have much say in the direction of the group, AFP has nearly 3 million citizen activists signed up to mobilize for candidates and policy causes. Taken together, AFP's grassroots volunteers and staffing rival those of the Republican party itself. By providing resources to support GOP candidates and officials, and exerting leverage on them once elected, AFP has been able to pull the Republican party to the far right on economic, tax and regulatory issues.
