I doubt that many DEAD Democrats will show up at polling places - they will simply file ABSENTEE ballots from the graveyard.
It's not the dead people...it's the people who are living, who are registered, but never vote (or haven't voted in 20-odd years). Suddenly places like, oh, *Philadelphia* will have tons and tons of absentee ballots coming from such people, where the statewide election is close.
Please, oh, please, someone post here telling me that they're looking out for this (images of Dem city officials handing out lists of people who never vote to ballot forgers crossing my mind).
