Michael Crowley wonders. At the risk of sounding like a broken record, here's what he should do: Invest heavily in New Hampshire and Iowa, as he's already doing, and see if his support in those states rises high enough to promise him a meaningful role in the GOP nominating process (and some delegates to take to the convention). If it does, great. But if he can't break 7 percent in a libertarian-friendly state like New Hampshire, I think he should strongly consider bowing out of the GOP race early, before too many "sore loser" provisions kick in, and pouring the rest of his money - and all the enthusiasm he's generated - into a third-party run as a Libertarian. The Giuliani-Clinton race that would have provided the ideal ground for such a bid looks less and less likely, but even in an Obama-Romney race (or any of the other permutations) Paul would still have more than enough oxygen for a national campaign. He's not going to have a better chance to take his message to the big stage, and if he isn't going to be a significant force in the GOP primary campaign, there's no good reason to have the Ron Paul Revolution die in mid-summer when it can last deep into the fall.
