Over 100,000 people rallied in Madison on Saturday against Wisconsin Republican Gov. Scott Walker’s effort to remove the collective bargaining rights of most public-sector workers. It was the largest demonstration Madison has seen since the Vietnam War. Tens of thousands of people marched in solidarity protests nationwide. In New York City, thousands gathered for a “Save the American Dream” rally outside City Hall. Crowds drawing several thousand were also reported in cities including Chicago, Columbus, Los Angeles and Denver. In Wisconsin, hundreds of demonstrators defied police orders and slept inside the State Capitol building Sunday night in defiance of Walker’s order to leave. Capitol police decided not to enforce Walker’s edict after hundreds of labor activists, students and supporters insisted on staying put.
