I honestly don't know. I see two primary camps in that prediction department.
One camp predicts that Gonzales will be a pick, nominally because the pick will energize Hispanic voters, and perhaps because Bush rewards loyalty (another crony pick), or because Bush wants to stick a needle in the eye of the uber-right-wing conservatives who objected to the Miers nomination, since he knows these same people object to Gonzales on the frounds that GOnzales has demonstrated judicial activism (see TX parental notification cases).
The other camp predicts that Bush will avoid a Gonzales pick, for the same reasons noted above. That he is not vindictive, and that he intends to honor his campaing promise to nominate strict constructionists, where "strict constructionist" can be fleshed out with the benchmark examples of Thomas and Scalia.
I have heard that JRB is pro-choice (only recently). Do you know if that's true?
She has been my first choice as SC nominee from the beginning, but if she isn't pro-life, I have a problem with supporting her.
Another reason to avoid the Gonzales pick is his alleged advice re definition of torture of terror suspects. That would open up anti-military territory for Schumer, et al to pursue.
