Some years ago, was either during Bush or Obama, I was watching the RNC primary convention, which for some reason I used to watch those things, and I noticed something odd, the Republicans were really stiff and not smiling. On occasion they would laugh, but it would be as if on cue, when somebody on stage told an obvious joke. But other than that, it was a bunch of cold mostly older white males.
Now the DNC convention, yeah, the Democrats are bunch of phones too, but at least they were smiling. Even when they didn't have to, they were smiling and showing other emotions.
