This sort of thing is why we desperately need voter id laws. Not only that but we need the indelible ink to prove who has and who hasn't voted. The dems are going to cheat so bad on this election that we need 10 or 15% or more just to make it even.
Voter id is only opposed by those who want to cheat on the vote. We know they lie about everything else, this is the most important thing they will ever lie about and we need to be able to stop them.
