Daily 3/12/2011 11:49:53 PM - (Madison, WI) -- Tens of thousands of people are expected to take part in a demonstration in Wisconsin's state capital Saturday.

Madison has been ground zero for a political showdown that included state Senators bolting out of town and thousands of people occupying the state Capitol Building, and now a massive demonstration is in store for the state.

Public employees are angry that Governor Scott Walker signed a bill into law Friday that does away with most collective bargaining for public workers.

The big event Saturday will take place outside the Capitol when people welcome the return of the 14 state Senate Democrats who took off to Illinois to stall a vote on the collective bargaining measure.
