Don’t quite see the big deal. There is a procedure for signature match. All this ruling did was insist that all counties use it. A ballot can’t be discarded because a local election judge uses his own decision rather than the state wide procedure.
Absentee ballots have been done like this forever.
Absentee ballots and this ballot system are different. This is mass mail-in ballots due to Covid (that is their justification for this). Absentee ballots have a set process and you register ahead of time and request a ballot.
If they do this with “mail-in ballots” it will simply be pure chaos. This is what they want. This is purely crazy.
