Stanley P. Miller is discussing:

"[C]ounty boards of elections are prohibited from rejecting absentee or mail-in ballots based on signature comparison..."

Signatures on a ballot are mostly worthless. The folks checking them are minimally skilled at detecting forgeries or dealing with normal changes in how one is written.

I don't like them at all but if they must be used then sequester the iffy ballots until the validity of the signature can be confirmed. Trashing them or accepting them are not valid responses.
