With unemployment among American Blacks double the rate for whites, the Congressional Black Caucus is distancing itself from the first Black president. Michigan Representative John Conyers recently said of the president: “We want him to know that from this day forward . . . we’ve had it…We want him to come out on our side and advocate, not to watch and wait.”Politically, the President is now in his worst fix yet. The Black Caucus isn’t going to endorse a Republican or even support a potential primary challenger, but if turnout drops as some disillusioned Black voters stay home, states like North Carolina, Virginia, Florida and Ohio begin to slip out of reach.A political Houdini like ex-President Clinton or Ronald Reagan might figure out how to please the Black base while reaching out to the center; so far, that kind of razzle-dazzle has not been one of this president’s skills.
