Sorry to keep harping on this, but why is Bush addressing the nation at 5:00 this afternoon? What's he going to tell us about the damage from Katrina? That it's bad?

I don't remember any president ever doing a nationally televised address in a situation like this. Fly over? Sure. Visit the scene? Absolutely. And in theory it would be appropriate for a competent president to ride herd on agencies coordinating relief. But this is just (as I keep saying) Bush's effort to own the tragedy.
