The 2004 United States Senate election in Georgia took place on November 2, 2004 alongside other elections to the United States Senate in other states as well as elections to the United States House of Representatives and various state and local elections. Incumbent Democratic U.S. Senator Zell Miller decided to retire, leaving an open seat. Majette became both the first African American and the first woman to be nominated for the U.S. Senate in Georgia. Republican Johnny Isakson won the open seat.
The results were almost a complete reversal from 2000.
Majette's announcement that she would seek to replace Miller also caught Democrats by surprise, as she was not on anyone's call list when Democrats began seeking a candidate to replace Miller. Further skepticism among Democrats about the viability of her candidacy surfaced when she announced that "God" had told her to run for the Senate. She received important endorsements from US Senators Mary Landrieu of Louisiana and Debbie Stabenow of Michigan, along with many others in Washington who campaigned and raised money for Majette. Her Senate campaign slogan was "I'll be nobody's Senator, but yours."
A number of factors led to Majette's loss. These include her late start, her valuable time and money spent in the runoff, larger conservative turnout from a proposed constitutional amendment banning same-sex marriages (which Majette opposed), the popularity of President George W. Bush in Georgia, and her lack of experience (being a one-term congresswoman).
