Why was Obama not in Florida when hurricane Gustav hit?

Why wasn't Obama in florida along side of the govenor when Hurricane Gustav was about to hit?When Hurricane Gustav was about to hit President Bush and Mccain flew to Florida,but Barack Obama stayed in his post in Detroit, Michigan. Many believe that Obama didn't go to Florida because the governor was a republican and he was democrat. But it seemed that John McCain and Barack Obama took time out from political bickering to both focus on Hurricane Gustav and helping the areas most in danger of the destructive storm heading their way. Many republicanss and some Voters feel the exact opposite, They feel that he didn't do much when Hurrican Gustav hit Florida. Obama was in Ohio getting people to donate money for the damage that Hurrican Gustav was about to make. While McCain flew to Florida to make preperations for the storm and to show his support.
