Kat-egory 2

The media (present company included, sometimes) can be pretty dense once it gets an idea in its head. Once a storyline is established -- hurricane threatens Republican convention! -- then shifting course is like turning around an aircraft carrier. It's been increasingly clear for the last day or two that Tampa is going to be sideswiped and that the real threat is more likely for beleaguered New Orleans. By the time the media picks up on that, I hope it's not too late for folks to get out -- the tragedy that wasn't averted in 2005.

I hope none of this comes to pass. But if Isaac does turn out to be a major hurricane and it does strike New Orleans, they should just scrap next week's Democratic convention altogether. The government needs to mobilize for real emergencies, not for prime-time windbaggery by Joe Biden & Co.
