When Landrieu announced he was running for the office his father, Moon, held in the 1970s, some people wondered what he was thinking (his sister Mary is also a Democratic senator from Louisiana). New Orleans hadn’t recovered from Hurricane Katrina, was racked by corruption, and had serious racial tensions exacerbated by the storm. Even if the white Landrieu could get himself elected mayor of the heavily black city, why would he want to? But while New Orleans still faces challenges, he’s impressed with efforts to rebuild the city and break corruption. If the Big Easy recovers, Landrieu will receive the lion’s share of the credit.
