"These people don't deserve this," Democratic Sen. Mary Landrieu told WVUE-TV near Braithwaite, a community flooded to the rooftops when a nearby non-federal levee was overwhelmed by Isaac's storm surge. "We have to fight harder and stronger for protection for everyone. You know, on one side of the levee it's completely dry. Houses are safe. Families are going back to normal. And on the other side, it's a nightmare."
