MADISON, WI (WTAQ) - A Democratic organizer says four Republican state senators will not be able to escape recall elections by convincing the state to invalidate thousands of petition signatures. Zac Kramer told the AP he made a cursory review of the challenges filed Thursday by the four senators – and he doesn’t believe the Government Accountability Board will uphold all those challenges. According to preliminary numbers, Senate Majority Leader Scott Fitzgerald is challenging 11,000 more signatures than he needs to have stricken in order to avoid a recall vote. Chippewa Falls Senator Terry Moulton is challenging about a hundred more signatures than he might need to ward off his recall. Kramer said Fitzgerald made a number of frivolous challenges that won’t stand – like counting some of his challenges twice, and wrongly claiming that some of the petitions did not have required information. Pam Galloway of Wausau and Van Wanggaard of Racine apparently fell short of challenging enough signatures to avoid their recall elections. But they still hope to invalidate more signatures, by asking that the GOP’s new hand-made Senate districts be used for the elections instead of the old ones drawn up by a federal court a decade ago. The new boundaries are not scheduled to take effect until this fall, pending legal efforts by Democrats and Hispanics to strike them down. Also, Fitzgerald said petitioners were improperly given 61 days to circulate petitions instead of the required 60, due to the King Day holiday last month.
