That very well may be true.
New Orleans is a place for Democrats to make up margins.
I remember a senate race @ 12 or so years ago with Miss Mary vs Suzanne Haik Terrell. Terrell was ahead all night, then - ta da! - in came the Orleans Parish votes needed to re-elect Miss Mary.
Looks like everyone called it for Edwards. I guess they found Edwards to be more conservative then Vitter....in some areas that may be true. The good news is Edwards rejected the refugees too. He will be tough on abortion. And as Governor he only can do what the State Legislatures allow him to do.
