I think the Dems are more angry because all they have to counter the photo of Bush on the rubble with a megaphone is a photo of Kerry running from the Capitol building to duck into his Limo.
I'm positive the Dems would replicate the same strategy if it were a Dem President. Picture Wm Clinton walking around moaning..."I feel your pain".
Politics is a nast arena, you must use what is yours to its fullest. Why not?
