Playing a game of political chicken, Democratic senators who fled Wisconsin to stymie restrictions on public-employee unions said Sunday they planned to come back from exile soon, betting that even though their return will allow the bill to pass, the curbs are so unpopular they'll taint the state's Republican governor and legislators.

The Republicans rejected the idea that the legislation would hurt the GOP. "If you think this is a bad bill for Republicans, why didn't you stand up in the chamber and debate us about it three weeks ago?" said Senate Majority Leader Scott Fitzgerald. "People think it's absolutely ridiculous that these 14 senators have not been in Wisconsin for three weeks."

The Wisconsin standoff, which drew thousands of demonstrators to occupy the capitol in Madison for days at a time, has come to highlight efforts in other states to address budget problems in part by limiting the powers and benefits accorded public-sector unions.

Sen. Mark Miller said he and his fellow Democrats intend to let the full Senate vote on Gov. Scott Walker's "budget-repair" bill, which includes the proposed limits on public unions' collective-bargaining rights. The bill, which had been blocked because the missing Democrats were needed for the Senate to have enough members present to vote on it, is expected to pass the Republican-controlled chamber.

He said he thinks recent polls showing voter discontent with Mr. Walker over limits on bargaining rights have been "disastrous" for the governor and Republicans and give Democrats more leverage to seek changes in a broader two-year budget bill Mr. Walker proposed Tuesday.
