Any true conservative would boo Bush, so that's kind of an unfair question.

That's a given. McCain tweaked the conservatives by cheerleading for Obama during the campaign and he lost the conservative base by doing so. McCain needs to wrap it up at this point and go find a rocking chair on a porch somewhere as his day in the sun is gone and done.
In fairness to Obama, the crowd wasn't booing Obama, they were booing McCain for being a toadie.
