Petraeus rules out run for president.

In a new interview with NBC News set to air tonight, Gen. David Petraeus rules out a run for elected office:

WILLIAMS: General, will you ever hold political office in this country?

PETRAEUS: Never. And I’ve tried to say that on a number of occasions. Some folks have reminded me of a country western song that says “what part of no, don’t you understand?”

Hear that? It’s the sound of K-Lo and Bill Kristol’s hearts breaking.
