In a nationwide Fox News/Opinion Dynamics poll of 900 registered voters conducted in July 2001, 44 percent of American respondents thought that Condit was involved in Levy's disappearance and 27 percent felt that he should resign. Fifty-one percent of the respondents believed that he was acting as if he were guilty; 13 percent felt that he should run again for office. A poll sample taken from Condit's congressional district held a more favorable view of Condit. On March 5, 2002, Condit lost the Democratic primary election for his Congressional seat to his former aide, then-Assemblyman Dennis Cardoza, with the Levy controversy being cited as a contributing factor. He was subpoenaed to appear on April 1, 2002, before a District of Columbia grand jury investigating the disappearance. The date was kept a carefully guarded secret to avoid further leaks. Condit left Congress at the end of his term on January 3, 2003, after failing to win his re-election bid.
