This probably won't end well. Following the President's State of the Union address tonight, Chris Matthews took to MSNBC's airwaves to declare that Obama is "post-racial," before stating, "I forgot he was black tonight for an hour." Update: Matthews "clarifies."

Update, 12:55 AM ET: Earlier this hour on Rachel Maddow's program, Matthews attempted to clarify his remarks, stating (in part), "I think [Obama]'s done something wonderful. I think he's taken us beyond black and white in our politics, wonderfully so, in just a year." Video of Matthews' full "clarification" is below.

Also, here is a more complete version of Matthews' original statements, including what he said after the remarks that made news.
