Your memory of the time period back then, like almost everyone, for some odd reason, seems non-existent. There actually wasn't much public debate at all over going to Baghdad or not. It was all over "how do we survive the thousands killed in a year or more of trench warfare retaking Kuwait" and whether it's worth it, and shouldn't we really sit around and wait for sanctions to be painful enough to cause Hussein to withdraw on his own...
Oh, I remember the time quite well, thank you. I'm not talking about "the public debate". Bush II paid zip attention to the "public debate" about Iraq. If Bush I had understood history a bit better, he would have come to the same decision as Bush II. Unfortunately, he had neither the brains nor the cojones to do so.
