Bush weighs in on Barack?

There is speculation from the Chicago Tribune Blog on whether or not President Bush was referring to Sen. Barack Obama (D-Ill.) when he said there are people currently conducting themselves as if they’ve already received the votes needed to validate their star status. During Wednesday's press conference, the President said:

And we've got good candidates running hard. And we're going to win. Now, I know that defies conventional wisdom here. I'm not suggesting anybody in this august crowd has determined the outcome of the election already, but they're running profiles on who this person is going to be running this office, or this one that's going to be -- magazines have got all kinds of new stars emerging when they haven't won the votes yet.

This seems to be an interesting critique, given the advice he gave to Senator Obama, which is noted in the Senator’s book, Audacity of Hope:

You've got a bright future. Very bright. But I've been in this town awhile and, let me tell you, it can be tough. When you get a lot of attention like you've been getting, people start gunnin' for ya. And it won't necessarily just be coming from my side, you understand. From yours, too. Everybody'll be waiting for you to slip, know what I mean? So watch yourself.
