MADISON, Wis. (AP) -- When Wisconsin Democrats launched their historic recall drive against Republican Gov. Scott Walker last year, it was all about getting back at him for stripping public workers of their union rights.

But last week new federal statistics emerged that showed Wisconsin lost more jobs last year than any other state. Now Democrats vying for a chance to face Walker in the June 5 election are working to transform the contest into a referendum on the governor's failure to jumpstart the state's stalled economy.

The two front-runners for the Democratic nomination, Tom Barrett and Kathleen Falk, have been blasting Walker for failing to create jobs.

Walker has met the attacks head-on, playing up state tax credits his administration handed to businesses and an economic revitalization project in Milwaukee.
