It's the 40th anniversary of the assassination of Martin Luther King, Jr. What to say? A friend emailed me a link to what is one of the most poignant commentaries on his murder: Bobby Kennedy's remarks that night to a crowd that had come to hear him deliver a campaign speech but instead had to be informed by the Democratic presidential candidate that King had been shot and killed in Memphis.

Listening to this speech--in the middle of another hotly contested Democratic presidential campaign--it's difficult not to ask, who today sounds more like the RFK of that moment: HRC or BHO? It's not close.
