WITH only two weeks to go before the election, talk has turned to the Bradley effect. The phenomenon is named for Tom Bradley, the African-American mayor of Los Angeles, who lost the 1982 California governor’s race even though exit polls predicted he’d defeat his Republican opponent, George Deukmejian. Some white people, the theory goes, tell pollsters they will vote for black candidates and then, once in the voting booth, don’t.
