Chris Matthews" " I forgot Obama was black tonight"

CHRIS MATTHEWS: "You know, I was trying to think about who he was tonight, and it's interesting: He is post-racial by all appearances. You know, I forgot he was black tonight for an hour. You know, he's gone a long way to become a leader of this country and passed so much history in just a year or two. I mean, it's something we don't even think about. I was watching, I said, "Wait a minute. He's an African-American guy in front of a bunch of other white people, and there he is, President of the United States, and we've completely forgotten that tonight. Completely forgotten it."
