The blame for part of this screw up has to start being placed on those who were too stupid to get out of the way. Many of those folks did have transportation and simply chose not to leave. They are the one's who kept electing the leaders they got stuck with during this crisis. Let's put some of the blame where it rightfully belongs.
The conservative part of the state, pretty much the rest of the state, has tried for years to get things done the right way. Yet those in NOLA who have been so used to getting everything given to them kept the state from making that progress because of their "voting patterns". If you will take note of who is trying to defeat the necessary budget cuts you will discover that they are in the Louisiana Black Caucus.
They are squealing loudly now because they can no longer influence the powers that be with their vote. They have lost too many folks to other regions of the country.
