ON STAGE: Who’s that up on the stage with farm worker leader Cesar Chavez, prominent supporter of numerous liberal causes? Could it be Orange County Republican Supervisor Gaddi H. Vasquez? . . . Indeed it could. Vasquez, above, is scheduled to be the keynote speaker for the U.S. Hispanic Leadership Conference this weekend in Chicago, at the session where Chavez will receive the nonpartisan organization’s National Hispanic Hero Award. . . . “My involvement is strictly the speech,” Vasquez says, declining to say whether he would agree to be photographed with Chavez, whom he hasn’t met.
