Three new national polls this week show Rick Santorum surging into the lead nationally among Republicans.
First Read: "So if you were to write the early history of this GOP presidential race, you'd have to make these two points, no matter who eventually wins the nomination: One, Romney is the on-again, off-again front-runner who holds almost every advantage (money, organization, endorsements, having run for president before) except the one that matters most: the hearts and minds of the base. And two, all it takes is a little good news (a primary victory, a strong debate performance) for a non-Romney lacking these advantages to give him a run for his money because of the one missing ingredient for the front-runner: passion."
