Can Bachmann Still Win?

Nate Silver gives long odds:

If I were to write a script involving Mrs. Bachmann winning the Republican nomination, it would probably require Mr. Perry’s campaign to be already in a somewhat weakened state prior to Iowa because of a gaffe or some other key misstep. Then, perhaps, a disappointing performance in Iowa could be more of a death blow to him, with Mrs. Bachmann getting her head-to-head match-up against Mr. Romney — a very challenging but not impossible task.
