Former House Speaker Newt Gingrich surged in the final days of the South Carolina primary to take a double-digit win. That was a win that most pundits had not expected a week earlier when they were confidently predicting that Romney would remain the frontrunner and was almost guaranteed the party's nomination.
The conventional wisdom is that Mitt Romney is unbeatable after he takes the New Hampshire primary. So what will happen after New Hampshire? Two more primaries are scheduled in South Carolina and Florida before the action finally comes to the Nevada caucuses.
