50% to 38%. Beshear was later elected governor in 2007. Louisiana Incumbent Democrat J. Bennett Johnston chose to retire. After the jungle primary election, state treasurer Mary Landrieu went into a runoff election with State Representative Woody Jenkins of Baton Rouge, a former Democrat who had turned Republican two years earlier. She prevailed by 5,788 votes out of 1.7 million cast, the narrowest national result of the thirty-three races for the U.S. Senate that year and one of the closest election margins in Louisiana history. At the same time, Democrat Bill Clinton carried Louisiana by a considerable margin of 927,837 votes to 712,586 cast for Republican Bob Dole.

Three witnesses claimed Miller had paid them to claim that they had either cast multiple votes for Landrieu or drove vans of illegal voters across town. The others told such bizarre tales that FBI agents dismissed their claims out of hand. It also emerged that Miller had several felony convictions on his record, including a guilty plea to attempted murder. The Democrats walked out of the probe in protest, but the probe continued. The investigation dragged on for over ten months, angering the Democrats and exacerbating partisan friction in the day-to-day sessions of the Senate Agriculture, Nutrition and Forestry Committee to which Landrieu was assigned as a freshman member of the 105th Congress.
