Campaign

During Moseley Braun's first term as U.S. senator, she was plagued by several major controversies. Moseley Braun was the subject of a 1993 Federal Elections Commission investigation over $249,000 in unaccounted-for campaign funds. The agency found some small violations, but took no action against Moseley Braun, citing a lack of resources. Moseley Braun only admitted to bookkeeping errors. The Justice Department turned down two requests for investigations from the IRS. In 1996, Moseley Braun made a private trip to Nigeria, where she met with dictator Sani Abacha. Despite U.S. sanctions against that country due to Abacha's actions, the senator did not notify, nor register her trip with, the State Department. She subsequently defended Abacha's human rights records in Congress. Peter Fitzgerald, a state senator, won the Republican primary, defeating Illinois Comptroller Loleta Didrickson with 51.8% of the vote, to Didrickson's 48.2%. Fitzgerald spent nearly $7 million in the Republican primary. He had a major financial advantage, as he was a multimillionaire. He ended up spending $12 million in his election victory. In September, Moseley Braun created controversy again by using the word "nigger" to describe how she claims to be a victim of racism. Most polls over the first few months showed Moseley-Braun trailing badly. However, after she was helped in the final month by notable Democrats such as first lady Hillary Clinton and U.S. Representative Luis Gutiérrez, three polls published in the last week showed her within the margin of error, and, in one poll, running even with Fitzgerald.

Results

The incumbent Moseley Braun was narrowly defeated by Republican Peter Fitzgerald. Moseley Braun only won five of Illinois's 102 counties. Despite this, the race was kept close by Moseley Braun running up massive margins in Cook County, which is home to the city of Chicago. However, it wasn't quite enough to win. Fitzgerald would only serve one term in the Senate. Fitzgerald initially intended to run for a second term. However, after many Republicans and Democrats announced their intentions to run, Fitzgerald decided to retire. Fitzgerald served from January 3, 1999, to January 3, 2005. On January 3, 2005, Fitzgerald was succeeded by Democrat Barack Obama.
