I find it hard to believe it will be that close but then again if you take all of 0’s dirty ACORN type tactics into account and getting dead people, people that use aternate alias identities to vote in multiple jurisdictions, previously illegal aliens that were granted amnesty, and people without mental competency to vote, maybe.
This election cycle seems to have this paradigm where 'rats are playing this game: "It's OKAY to cheat and steal, and we'll try EVERY which way and that away to do it - see if you can catch us!", whereas republicans find examples here and there of SOME instances of this, it gets largely unreported, and the game goes on.
This game has gone on for many a cycle, but today is very sophisticated. The "end game" is loss of the republic.
