March 22, 2012- WASHINGTON — Anyone wondering why the ultra-conservative billionaire industrialist Koch brothers are trying to seize control of the libertarian Cato Institute might want to look toward Wisconsin.
The Cato Institute is a Washington think tank with a long history of rigorous scholarship in the name of championing individual liberty. It's known for taking positions outside the conservative mainstream on issues like civil liberties, the war on drugs and U.S. militarism, regardless of the political consequences.
Charles and David Koch, by contrast, are all about winning. Their massive underwriting of bellicose Tea Party groups and super PACs appears to have three main goals: ousting President Barack Obama, busting unions, and reducing the tax and regulatory burden on companies like their own.
