Why do you think that putting ballots in drop-boxes is "fraudulent"?
I mean, I'm not from Georgia, so maybe they have a different way of voting than other states, but in the seven other states I've lived, the proper way to vote is to put your ballot into a ballot box.
So, if someone says, "Remember to put your ballot into a ballot box," I would simply respond, "Thank you, I'll make sure I do," or, "Thanks, I already did my civic duty, but thanks for the friendly reminder."
One of the problems with our current (soon to be ex) president is that he's got people thinking that voting is wrong.
Since when did Americans, let alone Republicans, think that voting was a bad thing?
