MSNBC'S Matthews: 'I Forgot He Was Black Tonight'

Who had the line of the night? Was it Obama’s condemnation of the Supreme Court, Justice Samuel Alito mouthing of the words “that’s not true,” or was it this instant classic from MSNBC’s most gaffe-prone host?:

Your reactions below. Oh, and to be fair, make sure to watch Matthews embarrass Dem. Rep. Alan Grayson and then Howard Dean, both post-Brown victory last week.

UPDATE: Matthews issues a “clarification” of his statement to Politico:

I think he’s done something wonderful. I think he’s taken us beyond black and white in our politics, wonderfully so, in just a year.
