Then headline is so drama queen. Disenfranchised? Maybe not. The article says Nevada's voting rolls, like so many other states'. is a mess. It could be that some of the voters are dead or maybe they moved away. If the voters moved away within Nevada, it's possible they will have received a ballot in their new location. If they moved out of Nevada, then they will either receive a ballot in the mail where they live or if there is no blanket mail-in balloting in that state, they can apply for a mail-in ballot or vote in person.
if anything, I'd be more concerned that this blanket provision of mail-in ballots will lead to duplicate voting. Someone could receive a ballot meant for a voter who once lived at that person's address, use it to vote by mail, then vote again under his own name. The voter who once lived in Nevada could also be voting once in Nevada and again at his or her new address in another state. More dead people could be voting by mail-in too.
In PA, there is no mass mailing of ballots; one has to apply and technically, there has to be a good reason to vote by mail, although I've been told this year anyone who applies will most likely be approved. There could be fraud that way too, but I prefer that procedure than mass mailings.
What I am concerned about is that melodramatic stories like this could lead to elimination of mail-in voting altogether, In that case, it will be those who can't vote in person who will be disenfranchised.
