I’ve observed two things from the Democratic National Convention: First, they’ve done a good job of teaching the dignitaries to clap in front of their own faces in case they get a close up during ovations. And Second, Bill Clinton is great at mugging for the cameras. When he sees the cameras on him, he breaks into a big smile, gets wet eyed, and when Hillary is speaking, mouths, “I love you,” and shakes his head just so proudly.
