As the crowd received McCain's gracious concession speech and booed the mere mention of Obama, I wondered if such a thing happened with previous concession speeches.  I was able to locate video of George Bush's 1992 concession and John Kerry's in 2004.  Neither speech was accompanied by boos when the loser mentioned his opponent.  The boos last night I think said a lot about the McCain supporters and the nature of his overall campaign, in spite of the excellent speech he gave last night.

Anyone have access to other concession speeches to look for the same thing?  Comments welcome.
