One of the best "gotcha" moments of the debate occurred when Kerry caught Bush conflating between Al Qaeda and Saddam Hussein. Bush said that "we were attacked" and so we had to respond by invading Iraq. Kerry not only pointed out that it was not Hussein that attacked us, but did it in a dramatic way that no one could miss.
However, did anyone else here notice that afterwards Bush showed his Iraq obsession two more times? In a discussion of Al Qaeda, Bush began to speak about going to "Ira..." then stopped himself knowing that he wanted something else. So he switched to a person and actually said "Saddam Hussein" before he corrected himself and finally got it right with "Bin Laden." I think this was after Kerry's gotcha moment, and he still couldn't keep them straight!
Any other Bush bloopers that people noticed?
