From the New York Times:
Mitt Romney is sharpening his warning to Republicans about the consequences of nominating Newt Gingrich, declaring in an interview on Wednesday: “Zany is not what we need in a president.” … “Zany is great in a campaign. It’s great on talk radio. It’s great in print, it makes for fun reading,” Mr. Romney told The New York Times. “But in terms of a president, we need a leader, and a leader needs to be someone who can bring Americans together.”
