Got to be a resident of NO to vote from there and effectively most of the folks aren't going to be Residents any longer. Those elections take place in November 06. Do you think they will all be moved back there by then First they got to lower the water then they got to tear down the mess then they got to rebuild all the infrastructure then the have to get utilities in there then the can start rebuilding the houses. A house takes 3-6 months to complete if everything is in place. Everything is not only not in place in ain't gonna be in place for a long time!
In the mean time these folks have to move on with their lives, They are going to start over in areas outside of NO. They will have to officially change residence to get their mail and start jobs and get insurance and cars and license plates and driver license and TAX returns and so on and so forth. Those on Government assistance will have to officialy change their residence to get their checks.
In effect most of New Oreleans is closed until further notice. Which means for the duration it is no longer a voting district.
