But Louisiana Governor Blanco did declare a state of emergency on the Friday before the storm. (Administration shills claimed she hadn't.) She then asked the president to follow through, which he did, and...well, you know what didn't happen then.
The point isn't to assess Bush's proportional responsibility for the weak federal response but to stress that this situation should not be used as a pretext to give the federal government more power. It may, however, be a great reason to fire the political appointees who staff FEMA (following the late but welcome resignation of Michael Brown) and to liberate that agency from the yoke of Michael Chertoff, who we could roast over some hot coals while we're at it. That would give the agency its former power without actually increasing that of the federal government. And it would give some stray New Orleans dogs some much longed-for, if stringy meat.
DISCLAIMER: I'm not suggesting Blanco, Nagin, Barbour, or anybody else down here be absolved of responsibility. But the early Administration "don't look at us" line was perfumed bullshit.
