In an unusually frank interview on Canadian public radio, CBC, Rep. Emmanuel Cleaver of Kansas City -- a Hillary supporter and superdelegate -- gives a sense of how tenuous Clinton's hold on many black superdelegates is.
"If I had to make a prediction right now, I'd say Barack Obama is going to be the next president," he said just after 18:00. "I will be stunned if he's not the next president of the United States."
He doesn't back off his support for Clinton, and has criticism for Obama:
"He is articulate - in the black tradition, he would probably be mediocre, but in White America..." he said, a bit dismissively, of Obama's speaking style, going on to joke about the word "articulate."
