Have you ever seen a mail in ballot? Have you ever used one? You sign an envelope but not the one your ballot goes in. Your ballot goes in an unmarked envelope which isn't opened until your ballot is counted. Do you think polls people conspire to try and record how people voted just on the off chance that police might want to know later? Of course if they did it would only be in the states Trump lost. Right? The trouble with your conspiracies is that so many people would have to be in on them with out one of them blabbing, they are an impossibility.
