Wisconsin Minority Leader Peter Barca, center, D-Kenosha, speaks as Republican Assembly members leave the chambers for caucus at the State Capitol in Madison, Wis., Friday, Feb. 18, 2011. The Wisconsin State Patrol was dispatched Friday to find a Democratic state senator who fled the Capitol to delay the near-certain passage of a bill to end a half-century of collective bargaining rights for public workers, a measure that's attracted thousands of protesters for four days.
