The most solid Democrat base of all, dead people.
This is all part of the 'flood the polls' strategy by Democrats. And it is happening nationwide. They want to create so many fake votes that the authorities cannot keep up with it all. The Democrat logic is, 'They can't check them all.' And even if they get caught, so what? Some Liberal judge will just let them go anyway. They always do.
Fake names, dead people, illegals, Mickey Mouse, Lois Lane, anything they can think of they will do. The only thing surprising about Democrats sending ballots to dead people, is that they bothered to send them at all. The more common thing is for a Dem operative to fill in the ballots in the name of the dead person and submit it themselves.
What makes it all even worse is that some members of the vote verification process are Democrats themselves, and will let anything slip through as long as the corpse and Lois vote Democrat.
