Rachel Maddow mentions Dana Milbank's quote, explaining how it is not what Obama said and how it came to be misattributed to him. She talks about other stuff, someone else talks about other stuff, and Pat Buchanan comes in reading Dana Milbank's quote and commenting on it as though they were Obama's words, despite the refutation of the quote in the media at large and the refutation given by one of the participants only several minutes earlier.

I only posted the video to illustrate that he can say 'A' only seconds after someone has explained, indeed, 'not A'. Whether or not you accept the explanation of 'not A', reasoned discourse requires addressing, rather than ignoring, such a statement.
