David Broder helps the president up into the booster seat ...

It took almost no time for President Bush to put his stamp on the national response to the tragedy that has befallen New Orleans and the Gulf Coast, a reminder that modern communications have reshaped the constitutional division of powers in our government in ways that the Founding Fathers never could have imagined.

Because the commander in chief is also the communicator in chief, when a crisis emerges the nation's eyes turn to him as to no other official. We cannot yet calculate the political fallout from Hurricane Katrina and its devastating human and economic consequences, but one thing seems certain: It makes the previous signs of political weakness for Bush, measured in record-low job approval ratings, instantly irrelevant and opens new opportunities for him to regain his standing with the public.
