What's a Tea Party to do?

With less than a week until the Iowa caucus, it looks like there are several scenarios that could happen, but they all lead to one conclusion: Either quickly or after a long battle, Mitt Romney becomes the Presidential candidate of the GOP. Either he wins Iowa, or comes in the top 3 in a very fractured caucus, then wins New Hampshire. He then goes to South Carolina, where he has the backing of the governor. But besides Newt, who else will campaign there? Will Paul? I'm sure he will. Perry? I think so, as he has the money. And either Bachmann or Santorum who gets very good in Iowa, one of them will campaign in South Carolina. So there's still 4 people that will vote by the Tea Party. So Romney might win in South Carolina, and then he'll win most of the states. But then, what will the Tea Party do? They don't like Mitt, so will they want a 3rd party against Democrats and the GOP, or will they not vote? I don't know. Probably, they don't know, either.
