In 1991, all elections in Louisiana except U.S. presidential elections followed a variation of the open primary system called the
jungle primary. Candidates of all parties are listed on one ballot; voters need not limit themselves to the candidates of one party. Unless one candidate takes 50% or more of the vote in the first round, a run-off election is then held between the top two candidates, who may be members of the same party. In this election, the first round of voting was held on October 19, 1991, and the runoff was held on November 16. In
1990, Duke mounted a campaign for the
U.S. Senate, losing to incumbent Democrat
J. Bennett Johnston. Leading Republicans repudiated Duke's candidacy, citing his history as a white supremacist. Public Service Commissioner
Kathleen Blanco, a Democrat, announced her candidacy in May 1991. Edwards was not impressed by her entry. It was the first time in 40 years a woman had seriously run for Governor but Edwards surmised she would not get out of single digits. Blanco, who came from
Acadiana, could have complicated Edwards' bid for a fourth term but after 100 days she suddenly withdrew and ran for
Public Service Commissioner again. Blanco would later be elected governor in her own right in
2003. Meanwhile, Governor Roemer was facing a potential opponent for the Republican support who could have denied him major party support he needed to stave off Holloway and Duke. Another prominent party-switcher, Secretary of State
Fox McKeithen, who withdrew from a 1990 U.S. Senate bid, actively explored a gubernatorial bid. His father, former Governor
John McKeithen, would prove to be a strong asset had he run, but in the end, McKeithen figured that his time had come and gone and ran for reelection as Secretary of State. == Primary election ==
