None, I already expect that. I know most of his supporters are not going to vote for the actual Republican nominee anyway - and Paul isn't likely to endorse the nominee either. Lets put it this way, when Paul fails to win GOP nomination, I'd guess by a 3 to 1 margin that his supporters will vote libertarian or for Obama anyway. If Paul goes 3rd party, my hunch is he will take more votes from Obama than he will the eventual Republican nominee no matter who it is.
Now that doesn't mean Paul isn't sleazy for doing this. It's pretty shady that he is using the Republican party label this way when he has no intention of actually supporting the nominee. When Paul leaves to run 3rd party this time, I hope he will never, ever come back to the GOP. He is not a conservative and does not belong in the Republican party - and pretty much everyone knows it.
I don’t think it is sleazy but if you do fine. Do you also think that Palin’s third party hints were sleazy? Just wondering.
