He was good...except the part where he tried to imitate Margaret Thatcher. Evev a woman sitting next to Lady Thatcher winced when he did that.
At first I winced, but then thought it showed just how close he was to the Reagans that he felt comfortable with a moment of levity. I'm betting President Reagan would have enjoyed it.
I was a bit shocked by that, but it is clear that he is really close to the Reagans.
