I’m guessing this column was written prior to the attack in Dallas. I’m sure the speech he was scheduled for today, but cancelled, would have taken all the latest things into account. This is early summer, few people, except for political junkies, are paying much attention. His acceptance speech will most likely have 150 MILLION viewers, and that is where he can really make his mark, because that will probably be the first time most of those watching will have heard one of his speeches all the way through.
I would say after the convention. He’ll get nasty enough to tick off a few delegates if done before.
