If you have a family member or friend who has a disability or limited mobility but is competent to vote, ask the person whether they still vote and whether they need help getting to the polls, voting at their long-term-care facility, or casting an absentee ballot. If the person needs help, offer your assistance. Signed, your friendly election official (poll worker)
"Declaration of incompetence to exercise certain rights. 1.
The court may, as part of a proceeding under s. 54.44 in which an
individual is found incompetent and a guardian is appointed, declare that the individual has incapacity to exercise one or more of
the following rights:
g. The right to register to vote or to vote in an election, if the
court finds that the individual is incapable of understanding the
objective of the elective process. Also, in accordance with s. 6.03
(3), any elector of a municipality may petition the circuit court for
a determination that an individual residing in the municipality is
incapable of understanding the objective of the elective process
and thereby ineligible to register to vote or to vote in an election.
This determination shall be made by the court in accordance with
the procedures specified in this paragraph. If a petition is filed
under this subd. 1. g., the finding of the court shall be limited to a
determination as to voting eligibility. The appointment of a
guardian is not required for an individual whose sole limitation is
ineligibility to vote. The determination of the court shall be communicated in writing by the clerk of court to the election official
or agency charged under s. 6.48, 6.92, 6.925, 6.93, or 7.52 (5)
with the responsibility for determining challenges to registration
and voting that may be directed against that elector. The determination may be reviewed as provided in s. 54.64 (2) and any subsequent determination of the court shall be likewise communicated
by the clerk of court."
I however as a poll observer as well, when I see such incidences do report them and fill out an official report so those votes can be reviewed by the proper authorities.
I'm thinking of people who have physical disabilities (temporary or permanent) or mild mental impairments or treatable mental illnesses who understand voting, know something about the candidates, and just need help with getting to a polling place or dropping off an absentee ballot.
