The Most Important Question Of The Night?

Joe Klein expects that the moderators at tonight's debate will bring up Romney calling Gingrich "zany":

This could be the crucial moment of [Gingrich's] candidacy. The most important thing: he will have to control his anger. In the past, he has used such opportunities to attack the press–he might not tonight, since it’s a Fox News debate–but he could say, "I don’t think it does the party any good for you and me, Mitt, to stand here attacking each other. That’s exactly what Barack Obama wants." And then he could make the case for himself.
