State Treasurer Kurt Schuller says recall petitions must be signed in presence of another person
Recall election season is underway again in Wisconsin, and there’s plenty of advice being bandied about. Sign the petitions, don’t sign them. You can do this, you can’t do that.
Some of it is deliberate confusion (or simplification) on the part of those who favor or opposed to recalling Republican Gov. Scott Walker and Lt. Gov. Rebecca Kleefisch. Some of it is just general confusion about laws and rules that until recently most had never encountered.
The rules for signatures gathered on recall petitions to be valid are relatively simple. Yet missteps or flaws will be used by election officials to disallow signatures, or by Walker’s team in challenges. That’s one reason recall organizers are hoping to collect up to 700,000 signatures, well more than the 540,208 valid signatures required to trigger a recall election.
A key rule governing the petitions is meant to insure that they are signed in the presence of someone called the "circulator."
