If I voted in New Orleans or Louisiana, I would be looking at ways to initiate referendums asking the both the governor and the mayor to resign. If they refused to resign, I would begin initiating efforts aimed at recall or impeachment. There are months to years of rebuilding ahead that are still going to require substantial leadership for the City and the State. These two individuals have clearly demonstrated their incompetence to lead or organize.
