MADISON, WI (WTAQ) - Wisconsin election officials brought up the possibility today of using statistical samples instead of full actual counts, to determine how many false-and-duplicate signatures are on recall petitions except those against the governor. State Government Accountability Board director Kevin Kennedy says his agency is committed to checking all of the estimated one-million signatures for Governor Scott Walker’s recall election with the help of a database. But for the other recall petitions, Kennedy said the Board might use statistical sampling methods similar to those used in Nebraska, Washington, and other states. A decision on that is expected by Friday. An estimated 900-thousand signatures were submitted demanding recall votes against Lieutenant Governor Rebecca Kleefisch, and GOP senators Scott Fitzgerald, Van Wanggaard, Pam Galloway, and Terry Moulton. The Accountability Board has until March 19th to verify the recall petitions submitted three weeks ago.
