I Sense a Big But Coming

I've always been wary of the "big but." I'm not talking about anatomy of course. That's spelled differently. No, I'm talking about those big buts in the middle of a compound sentence that lay waste to everything said before the big but. An example might be: " I normally agree with you, BUT I think you're wrong about this."
After savaging George Bush at every opportunity, Tom Daschle has taken notice of the wind's direction, and poll number that show his seat is in jeopardy next year, and has commended the President's war time leadership. He mangaged to stifle his BUT for now, BUT, we all know it's coming.
