Our Second Black President

After praising President Bush for having a "post-racial management style" in his relationship with Condi Rice, Andrew Sullivan makes a bizarre statement. "You know, Bill Clinton was celebrated for his progressiveness, and ease with African-Americans. But it's inconceivable that he would have given so much power and authority to a black female peer."
Clinton, in fact, never appointed a woman to run the State Department, and will never have the chance; but how does Sullivan know such a thing is "inconveivable?"
