Madison, Wis. (Learfield) - The first of 16 efforts to recall Wisconsin politicians will move forward if enough petition signatures are valid. Democrats say they have collected petitions bearing 21 thousand, 700 signatures to recall state Senator Dan Kapanke. Democrats are trying to recall eight Republicans who backed the governor's union rights law. It will take about a month for the signatures to be validated. Recall elections would be held on the first Tuesday, six weeks after an adequate number of petition signatures are found to be valid. Meanwhile, Republicans are also collecting signatures in an effort to recall eight Democratic lawmakers.
