Joshua Bolten is the White House Chief of Staff who replaced Andy Card. Before replacing him, Bolten was Card's assistant. In other words, Josh Bolten is Andy Card 2.0.
Beyond his striking ability to yea-say with even more ardor than his predecessor, Bolten has distinguished himself by being slightly less overtly aggressive toward The Greatest President's enemies. While he seems to exude the same bland vanilla pudding charmlessness of all loyal Bush Administration officials, Bolten may nonetheless lack a certain vigorous pungency in the after-taste that Americans have come to know and expect of their "Bush Men." He just doesn't have the bite of a Karl Rove, the kick of an Alberto Gonzales, or the sour zing of a Tony Snow.
Who are you, Josh Bolten? Will the world ever know??
