How tall is Bill Kristol? I was shocked when I saw him....on screen, you'll notice that he is always seated.
NYC mayor Mike Bloomberg also seems to be very short when standing behind a lectern during a press conference. And I've had people tell me that Rudy Giuliani is "tall," but I saw him on a street corner in Manhattan years ago and he's at least six inches shorter than me (I'm 6'1").
Howard Dean is another small guy. Rumor has it that he never had his wife campaign with him because she's so much taller than him (people might remember that in the one television interview they did together, they were both slouched down on a couch so you couldn't really notice how tall they were).
