In her latest op-ed, Peggy Noonan writes:

In the Republican base, that huge and amorphous thing, judgments are less tough, more forgiving. But there too things have changed.

There remains a broad, reflexive, and very Republican kind of loyalty to George Bush. He is a war president with troops in the field. You can see his heart. He led us in a very human way through 9/11, from the early missteps to the later surefootedness. He was literally surefooted on the rubble that day he threw his arm around the retired fireman and said the people who did this will hear from all of us soon.

Images like that fix themselves in the heart. They're why Mr. Bush's popularity is at 38%. Without them it wouldn't be so high.

But there's unease in the base too, again for many reasons. One is that it's clear now to everyone in the Republican Party that Mr. Bush has changed the modern governing definition of "conservative."

He did this without asking. He did it even without explaining. He didn't go to the people whose loyalty and support raised him high and say, "This is what I'm doing, this is why I'm changing things, here's my thinking, here are the implications."
