The various Democrats who are advocating for mail in voting are the same people filing the lawsuits to prevent signature verification.
Back when real ID cr@p was being halfheartedly being instituted they required everyone to sign documents using full name on our birth certificate. The fact that I never had signed my full name anywhere because it was misspelled on my birth certificate didn't matter so my signature doesn't look anything like something I signed. I would be happy to include a thumbprint on ballot that can be matched with DMV records. Most states I think require that anymore.
