Did Rick Santorum almost call Barack Obama a nigger?

[mediamogul]

To me it honestly sounds as if he's starting to say the word "nigger". I can't imagine Santorum being that foolish. I know that people who use these words frequently often let them slip when in public and this looked like a slipl

My question is what other word might he have been trying to say? Any guesses?

He doesn't even finish the sentence after the slip. He gets a look on his face like he almost messed up and then moves on quickly. Frothy has racist painted on his forehead. I would not it past him to use that word in his private life.
