Lt. Gov. Mitch Landrieu (D), the son of former New Orleans Mayor Moon Landrieu and brother of Sen. Mary Landrieu (D-LA), has entered the field to challenge current Mayor Ray Nagin.

Landrieu said five principles will guide his rebuilding vision:

* Diversity is a strength, not a weakness.
* Louisiana’s economy must be expanded and diversified.
* New Orleans must work regionally to compete globally.
* Value must be added to raw materials, native talent and intellectual capital.
* Trying to achieve Southern average standards is not good enough.
