The 1992 United States Senate special election in California took place on November 3, 1992, at the same time as the regular election to the United States Senate in California. Feinstein defeated future California governor Gray Davis in the Democratic primary, while Seymour defeated William E. Dannemeyer in the Republican primary. In this special election to complete the unexpired term of Republican Pete Wilson, who resigned to become Governor of California, incumbent Republican Senator John Seymour was defeated by former San Francisco Mayor Dianne Feinstein, whom Wilson defeated in the 1990 gubernatorial election. Feinstein subsequently held seniority over fellow Democrat Barbara Boxer, who was elected on the same day; because Feinstein was elected to complete an unexpired term, she took office on November 4, only 1 day after the election, while Boxer's term commenced with the beginning of the next session of Congress in January 1993. These elections marked the first time in history that two women simultaneously served in the Senate from the same state.

Background

The seat became vacant after incumbent Republican U.S. Senator Pete Wilson won the 1990 gubernatorial election, defeating Democrat Dianne Feinstein. Wilson appointed John Seymour to the Senate to replace himself.
