We don't really know what Bush will do in the voting booth, but this story has legs because it fits a paradigm that so many have had for so long. And that is that the Republican elite support Leftists more than they do patriots, or wacko-birds as McCain calls them.
I would not doubt that many in the Republican leadership will be voting for Hillary. The status quo means more to them than the fate of America and Americans.
I still suspect that McCain voted for Obama twice, including against himself. The pathetically gushing way McCain praised this nobody loser from Chicago makes me think that way.
