VOTERS ARE REQUIRED TO SIGN THE POLL LIST
2011 Wisconsin Act 23 (the “Photo ID” legislation) requires a voter to sign the poll list, unless a disability prevents the voter from doing so.
“…each eligible elector…shall state his or her full name and address…The officials shall then require the elector to enter his or her signature on the poll list.., unless the elector is exempt from the signature requirement due to a disability…” (paraphrased). §6.79(2)(a), Wis. Stats.
If you are not prevented from signing because of a disability, and you refuse to sign, you will not be issued a ballot.
If the inspectors do not believe your claim that a disability prevents you from signing, you may be required to vote a challenged ballot.
