Former Sierra Club Pres. Adam Werbach is eying the mayorship of San Francisco and plans to decide in the next two weeks whether to make a run this November. The 26-year-old environmental wunderkind, who still serves on the Sierra Club board, has hooked up with a campaign consultant who once worked in Bill Clinton’s “war room” and media company North Woods Productions, which made the famous ads for Minnesota Gov. Jesse Ventura’s campaign featuring a Jesse action figure duking it out with “Evil Special Interest Man.” Werbach could face incumbent Mayor Willie Brown (D), among other candidates.
