After Wisconsin Governor Scott Walker signed a controversial bill stripping public union workers of their collective-bargaining rights, huge crowds in the tens of thousands that protested last weekend are expected to protest again Saturday, the first weekend since the bill’s signing. A week ago, Madison Police estimated the Saturday demonstration to approach 70,000 to 100,000 people, marking the largest demonstration at the state capitol since the Vietnam War. Several of the Democratic state senators who fled Wisconsin to boycott the bill and stall its approval are expected to attend the rally. "Saturday's going to be huge," said Terese Berceau, a Democratic member of the state Assembly who represents Madison, a university town that has seen its share of protests over the years. "Absolutely huge."
