his work in katrina showed he is a good leader that can handle a national crisis, Obama never proved that and still hasn't
Let me deal with that a little more. As someone who lives in South Mississippi, I was personally affected by Katrina. I left for North Alabama to stay with some family the day before it hit, and wound up being there for a week and a half due the damage in the area. And I live probably 70 miles inland.
Since I wasn't in the affected area during the storm (even though we were without power for 18 hours as far away from the "action" as I was), I was able to see the news coverage of the storm. I think the disastrous response by the elected officials in Louisiana is well-documented. But, Alabama's officials didn't do much better. Gov. Riley didn't declare a mandatory evacuation until 18 hours before landfall. Only 18 hours before that caused the USS Alabama battle ship in Mobile Bay to list to one side. Only Camille had ever moved the ship and it just rocked a bit then. So, considering the magnitude of the storm, Riley definitely should have done more to prepare the people.
Compare that to Mississippi. Barbour issued an evacuation order well in advance of the storm, and on Sunday morning when it had exploded into a category 5 monster, he made it quite clear to inland residents that we needed to be prepared, as well. I don't know how many times I heard him say "this is not just a coastal storm," or some variation of that.
Barbour really shined compared to both Riley and Landrieu. He was the only governor from the affected States that came out smelling like a rose.
