Dozens of protesters who camped out in the Wisconsin Capitol overnight said Friday they?re prepared to stay as long as necessary while an anti-union bill remains under consideration. As many as 25,000 protesters descended on the Capitol on Thursday for a full day of raucous chanting and peaceful demonstration. Several hundred, including UW-Madison students, spent the night, some bundling up in pajamas under blankets and in sleeping bags while others simply used their jackets as pillows and slept in street clothes.
