GREEN BAY, WI (WTAQ) - Madison Democrat Kathleen Falk will start a two-day tour of Wisconsin Tuesday to promote her candidacy for the possible recall election against Governor Scott Walker.

Falk, a former Dane County executive, will head to Milwaukee, Green Bay and Wausau Tuesday.

She’ll visit Eau Claire and La Crosse Wednesday.

So far, Falk is the only Democrat to announce her bid against Walker. Others are expected to throw their hats in the ring once state officials verify the 540,000 valid petition signatures needed to order an election.
