Mrs. Clinton, speaking to a black church audience on Martin Luther King Day last year, did describe President George W. Bush as treating the Congress of the United States like 'a plantation,' adding in a significant tone of voice that 'you know what I mean ...'

She did not repeat this trope, for some reason, when addressing the electors of Iowa or New Hampshire. She's willing to ring the other bell, though, if it suits her. But when an actual African-American challenger comes along, she rather tends to pout and wince at his presumption (or did until recently).
