A political action committee formed by a coalition of unions active in state recall races says it has raised more than $4 million in the past six weeks, and has $2 million on hand to help Democrats.

Its goal is to flip the state Senate to Democratic control.

In a filing prepared for the state Government Accountability Board, We Are Wisconsin listed more than $3 million in donations from the national AFL-CIO's Committee on Political Education. The group also received contributions in the hundreds of thousands of dollars - both cash and in-kind - from units of the American Federation of State, County and Municipal Employees; the Wisconsin Education Association Council, the state's biggest teachers union; and the United Food and Commercial Workers.

Kelly Steele, spokesman for We Are Wisconsin, said the $4.23 million total collected so far could grow before the report is filed as required Tuesday with the board.

A separate report laying out the group's expenditures lists some $350,000 in TV advertising - with the largest amounts spent in the districts of Republican Sens. Dan Kapanke of La Crosse and Sheila Harsdorf of River Falls.

But the group said it's still being outspent on TV by the conservative Club for Growth Wisconsin.

Six Republican and three Democratic state senators face recall elections this summer that sprang out of the battle in Madison over Gov. Scott Walker's bill to restrict collective bargaining for most public employees.
