Dixon was generally considered a moderate and was less visible nationally than either of his Illinois colleagues,
Charles Percy and
Paul Simon, both of whom sought the presidency. In 1992, Dixon lost in the Democratic primary for U.S. Senate to
Carol Moseley Braun. This defeat shocked observers; at the time no senator had been defeated in a primary in over a decade and Dixon had a long record of electoral success.
His vote to confirm
Clarence Thomas to the
Supreme Court contributed to his defeat. Dixon was sharply criticized during the campaign by Braun for supporting Clarence Thomas' nomination despite allegations of Thomas sexually harassing Anita Hill. Braun, a black woman, had the complete support of black voters, and as a known reformist liberal got a large share of liberal voters, and also attracted many women voters in what was termed "The Year of the Woman". Another factor was the third candidate in the race, multi-millionaire attorney Al Hofeld. Hofeld drew away some of the moderate and conservative Democrats who normally supported Dixon. He also spent a large amount of money running advertisements attacking Dixon, weakening his support. The
Chicago Tribune ran a piece in which
Eric Zorn claimed that Dixon's voting to confirm Clarence Thomas in 1991 set off a chain of events that led to
Barack Obama's election as president in 2008.
Later life and death Dixon chaired the Defense
Base Realignment and Closure Commission in 1994 and 1995. After his term in the Senate, Dixon resumed practicing law with the
Bryan Cave law firm in
St. Louis and lived in
Fairview Heights, Illinois, where he died on July 6, 2014, from
natural causes just 1 day shy of his 87th birthday. His autobiography,
The Gentleman from Illinois: Stories from Forty Years of Elective Public Service, was published in 2013 by
Southern Illinois University Press. ==Awards==
