Sure, but how many would vote Libertarian, or stay home? Surely the Republicans can put up someone so bad that this becomes a viable option.
I hope the Repubs nominate an outsider that has not been a career or DC politician. Someone that will cut spending like what Greece and Spain are doing. I don't think there is a politician on the hill that would propose that bitter pill. Spending is out of control and needs to be cut sharply.
