I agree with the judge. Because I do not remember if I signed voter registration in lower case or upper case. And there is no way for me to find out. I have a habit of using both when signing depending on my mood at the moment.

If you don't think your signature would match, then vote in person, with a valid ID.

Same problem can occur at in person voting? You have to sign and what if signatures don’t match exactly ??
Get on with modern technology.
Use thumb print for ID. It is fool proof.
