Input: Question: Who did Bruce Herschenohn run against in his primary? Passage:In 1992 four-term incumbent Democratic Senator Alan Cranston retired, creating an open seat contest. In what was billed as the "Year of the Woman", Boxer beat fellow Rep. Mel Levine and Lieutenant Governor Leo McCarthy in the Democratic primary, winning 44% of the vote. In the general election, Boxer defeated Republican Bruce Herschensohn, a conservative television political commentator from Los Angeles, by 4.9%. A last-minute revelation that Herschensohn had attended a strip club at least partially affected the outcome. In 1998, she won a second term, beating sitting California State Treasurer Matt Fong by 10.1% of the vote. After facing no primary opposition in the 2004 election, Boxer defeated GOP candidate Bill Jones, the former California Secretary of State, by 20%. In 2010, Boxer defeated GOP candidate Carly Fiorina, former chief executive officer of Hewlett-Packard, by 10%.
