Fiedler's role in the grass-roots group helped propel her to public office, as she won a surprising upset in 1977 against Los Angeles school board president Robert Docter, who favored desegregation busing.

Corman's campaign manager, Clint Reilly, later recalled that his candidate's position on racial integration drew heavy fire from Fiedler, whom he described as "the leader of LA's anti-busing movement."

Reilly noted that the Republican Party raised more than a million dollars for Fiedler, and "the campaign was waged in the racially charged atmosphere of the San Fernando Valley."

When Goldwater decided to run instead for the U.S. Senate, Fiedler had only token opposition in the GOP primary and won an easy re-election later that year in the heavily Republican district.

In 1986, Fiedler did not run for re-election to the House of Representatives, opting instead to make what proved to be an unsuccessful bid for the Republican nomination to challenge three-term Democratic incumbent Alan Cranston for his United States Senate seat.

She was charged with political corruption in January 1986 after an undercover investigation allegedly showed that Fiedler offered $100,000 to a rival, State Senator Ed Davis (R), if he would withdraw from the Republican senatorial primary.
