Basing my grades entirely on crowd reactions at today’s NRA “Celebration of American Values,” I’d grade McCain B+, Thompson A, Rudy B+, Huckabee A+. I will give Romney and Richardson C+s for their video presentations – they’re well done for what they are, but no video can command an audience’s attention the way a candidate in the flesh can. Duncan Hunter is scheduled to appear by video later today. Newt Gingrich is also expected to appear, in person, but unless he gets his $30 million by November, he’s not in.
