I also found this while researching New Orleans..........
Before his election, Nagin was a member of the
Republican Party and had little political experience; he was a vice president and general manager at Cox Communications, a
cable communications company and subsidiary of
Cox Enterprises. Nagin did give donations periodically to candidates, namely President
George W. Bush and former Republican U.S. Representative
Billy Tauzin in 1999 and 2000, as well as to Democratic U.S. Senators
John Breaux and
J. Bennett Johnston earlier in the decade.
Days before filing for the New Orleans Mayoral race in February 2002, Nagin switched his party registration to the Democratic Party, presumably in order to improve his chances of winning the race in heavily Democratic New Orleans. Shortly before the primary election, an endorsement praising Nagin as a reformer by
Gambit Magazine gave him crucial momentum that would carry through for the primary election and runoff. In the first round of the crowded mayoral election in February 2002, Nagin received first place with 29% of the vote, against such opponents as Police Chief
Richard Pennington, State Senator
Paulette Irons, City Councilman
Troy Carter and others. In the runoff with Pennington in May 2002, Nagin won with 59% of the vote. His campaign was largely self-financed.
