Politico.com examines the behind the scene effort to take down public sector unions in Wisconsin.

The web story is long, but worth reading because it identifies groups who are influencing elected officials in Wisconsin and other states to reduce government salaries and benefits.

Think-tank groups like the American Legislative Exchange Council and Wisconsin’s MacIver Institute and Ohio’s Buckeye Institute for Public Policy Solutions have received millions of dollars for their “doom and gloom” research warning lawmakers to control spending on workers’ benefits and pensions, etc.

The groups have depended on the generous support of billionaire brothers – Charles and David Koch, owners of Koch industries and other conservative donors and organizations.
