You beat me to it!
As a proud Wolverine, that was my favorite Kerry gaffe of '04. (I know, I know, it's hard to pick just one.) I wish I'd been there as the booing from his hand-picked supporters arose just to see the look on his face. Then, when he realized what he had done, he started stammering about "Well, that was what I was saying earlier today, when I was in Ohio, I know you folks have your... 'Big Blue'..." The guy would have paid a thousand smacks for someone to whisper the word "Wolverines" to him just then! Karl Rove must have giggled himself stupid over that one.
Over the following few days Pres. Bush did several Michigan events and I eagerly read his introductory remarks at each one knowing for sure Kerry's blunder wouldn't go unremarked. "Well, I'm sure that's not what you folks here in Michigan were expecting to hear..." No, Mr. President, it certainly was not! LOL!
That was probably my favorite gaffe of his many. It just showed how clueless he was (and is) to the real world, not the faux royalty one he has to imagine himself in.
