Sarah is smart to say something like this, not only because she is right, but also because it may help dissuade Paul from launching a certainly disastrous third-party bid.
Paul is a bit nutty about some things, but he is dead-on about spending and about the Fed. And we need to keep him in the Republican party.
So many keep bringing a potential "Ron Paul third Party" run, in spite of the fact that the man has done everything but swear on his firstborn that he has no plans for it. It is Ron Paul's plan to win the Republican nomination.
If people do want to think about realistic third Party runs, Gary Johnson has already said that he is considering it given the treatment he has gotten within the Republican Party. If Ron Paul loses the nomination, it's possible that Johnson could pick up the Ron Paul votes screwing over whoever is the nominee.
And before you think that is dirty pool --even though it's not planned that way -- there is another realistic potential 3rd Party contender to muddy the waters if things aren't going his way -- and that is Donald Trump. Trump said that after moderating this debate, if he didn't like what he saw, he'd run himself. Personally, my bet is that Trump would jump into the race ONLY if Ron Paul became the Republican nominee. He'd rather contribute to Obama 2nd term and see the Republican Party explode into flames than change the DC status quo that is his low interest loan gravy train for real estate investments. (So why should any respectable Republican candidate be kissing the Donald's ring or even appearing in the same room with him?)
