And if not....if you think that Bush seriously bungled it in a way that wasn't inevitable, did he bungle it because he's incompetent or did he bungle it because he didn't care? If the latter, then yeah, having it take place before the election would have changed the response significantly. But if he bungled it because he's incompetent, then it doesn't matter when the timing of the storm would have been. He'd have messed it up anyway.
I think that's a false dichotomy.
The man is incompetent and cares about very little except where his next pretzel is coming from. But he does listen to his political advisers, and tries to do what they tell him. And they'd have reacted much quicker - there'd simply have been far more of them - if it happened during a presidential campaign.
Obviously,
some sort of negative publicity was inevitable. A lot depends on the exact timing.
