Jim Costa is running for the seat vacated by Democratic Rep. Cal Dooley, who decided not to run for re-election. Dooley's retirement prompted a contentious contest between Costa and Lisa Quigley, Dooley's former chief of staff, who he endorsed.
Costa won the March 2004 primary with 73 percent of the vote, tarring Quigley as a carpetbagger with no electoral experience. Quigley attacked Costa's voting record and his recent work as a lobbyist. Costa will face Republican state Sen. Roy Ashburn in the November 2004 election.
