He leaves the option open:

If you don't win, will you support the GOP nominee and promise not to run on the Libertarian or any other ticket?

I'm not promising any of those things. If we have a Republican nominee that has convinced me they have come around on foreign policy … I would consider it. As far as running on a third-party ticket, or [as an] independent, or Libertarian, I have no plans to do that.

Well, "no plans" doesn't mean you won't.

The best way I can state it is: I have no plans. I can't conceive of it. But I guess in life there aren't that many absolutes.

The combination of a more prudent foreign policy - including withdrawal from Iraq - and a dismantling of the police/torture/surveillance state could be potent in a general election, if Paul loses the GOP race. Who would run with him?
