They say every cloud has a silver lining. In this case, the silver lining will apparently keep President Bush and VP Dick 'The Smirk' Cheney out of the Republican convention - it may even keep John McCain off stage. The silver lining is in the fewer comparisons to the Demo-spectacle, the better, because McCain is no McAble when it comes to crowd-rousers.
They say he is showing concern for the people of New Orleans. As I write this, Gustav is still offshore, but has diminished to a category 2: nothing to be sneezed at (especially into the wind.) "Acting presidential" is the role McCain has taken on... but other than showing concern and holding off the balloon drop, I don't really see what he can DO beyond expressing concern.
Meanwhile, Bush is here in Austin.
Later, he should tour any New Orleans devastation with Michael Brown hanging upside-down from a rope beneath the helicopter.
