Re JGP’s comment: “Even if Paul doesn’t thrill you, whether it’s legitimate to lock him out is another question.” It probably wouldn’t be legitimate for the Republican party to do so; Paul is out-polling Thompson in New Hampshire, after all. The NH GOP was right to pull their co-sponsorship. But it’s perfectly legitimate for Fox News to invite whoever they want to appear before the cameras they own, as Ron Paul himself ought to agree (at least when he’s not ditching his principles).
