The link at the end is sadly amusing, a CBS News story from Hurricane Charley in 2004:

Even before many residents were allowed back into their own homes, President Bush headed to Punta Gorda for his own first hand look, getting a bird's eye view from his helicopter and a quick briefing from his brother the governor and local leaders.

Consoling those who have lost everything, Mr. Bush assured devastated residents that help is on the way.

"The government's job is to help people re-build their lives and that's what's happening," he said.

Even before the storm hit, the president declared four counties disaster areas to speed federal money to victims. But that quick response fueled suspicion that he is using disaster politics to help his campaign in one of the most critical battleground states, a notion the president dismissed Sunday.

"Yeah, and if I didn't come they'd have said he should have been here more rapidly," Mr. Bush said.

The president is trying not to repeat his father's mistakes. After Hurricane Andrew flattened parts of south Florida in 1992, state officials blamed the first President Bush for not answering their calls for help quickly enough, and trying to make up that by overcompensating later.

It's a lesson the current president and political analysts have not forgotten.

"President Bush Sr. put so much money into the state after Hurricane Andrew that he was accused of buying votes in that election. So there is potential that the president could float so much money into Florida that people would say that's political opportunism," says political analyst Craig Crawford.

There's still plenty of opportunity for missteps in the "disaster politics" ahead. Charley was just the first major storm in a hurricane season that will continue right up to the November elections.
