The so-called base made it personal by insulting Miers and dragging her name through the mud, never giving the woman a chance at the hearings. You think that Dubya's going to "reward" the base for such behavior? Look for a much more moderate female.
No, the vast majority of the base *didn't* make it personal. They pointed out evidence that Miers was by no means a conservative on a wide range of issues.
Also, your suggestion that Bush is going to choose the next Supreme Court nominee based on some sort of snitty pique at conservatives is hardly a compliment. I think they call this "projection."
