As much as I like Newt, in many ways, the fact is, he did lose his campaign staff, at one time, and had to rebuild.
So did McCain in 2008 IIRC. It's still too early to anoint Mitt as the Republican standard bearer. Despite what keeps happening to the flavors of the months, he never gains from it. Mitt is the front-runner and likely GOP nominee, but it is absolutely not inevitable. Nor is it inevitable that Newt will end up being the one who becomes the final Anti-Mitt. Rick still has a shot at that title, tho he'll need Newt to stumble as all the others have before.
