I do think George is very partial to not only Hillary but Obama also. Though to be fair he said some in the party might see Obama as unelectable because of the Wright fiasco.
As far as Obama and his "brave and thoughtful speech" no conservative would have gotten away with the words that Obama preached if they were about white bigotry. First off, the conservative would have never been able to survive the close association with a white racist (remember Wright was Obama's spiritual advisor). Secondly, if they found some way to survive the nuclear blast from their association they would be instantly vaporized for not cutting all strings to that association. Obama is unwilling to remove himself from the grounds where black racism is given the pulpit. This, rightfully so, makes those who preach white racism unelectable. The same results should be expected for Obama.
