In all fairness, the signature provision is relatively new. Not all poll workers are familiar with it. The confusion happened with new registrations. Seems to me that they should halt registrations at the polls. I think Racine had about 4000 on election day. That is where the problem lies.
There seems to be NO problem with the fact that being unwilling to disenfranchise an “illegal” voter just happens to effectively disenfranchise a LEGAL voter, especially among the holders of a certain political view. Curious, isn’t it?
