Independent presidential candidate Ralph Nader selected Matt Gonzalez, a former member of the San Francisco Board of Supervisors, to be his running mate.
Nader, who launched his fourth White House bid last weekend, made the announcement Thursday at a news conference. The Texas-born Gonzalez ran for mayor of San Francisco as a Green Party candidate in 2003 but lost to Gavin Newsom.
When Nader announced his third-party campaign for the president last Sunday, he criticized the top contenders as being too close to big business. He also dismissed the possibility that his candidacy could tip the November election to Republicans.
The longtime consumer advocate sought the White House in each of the last three presidential elections: He ran on the Green Party ticket in 1996 and 2000, and as an independent in 2004.
Nader is still loathed by many Democrats who call him a spoiler and claim his candidacy in 2000 cost Democrats the election by siphoning votes from Al Gore in a razor-thin contest in Florida. Nader has vociferously disputed the spoiler claim, saying only Democrats are to blame for losing the race to George W. Bush.
Though he won 2.7 percent of the national vote as the Green Party candidate in 2000, Nader won just 0.3 percent as an independent in 2004, when he appeared on the ballot in only 34 states.
