Reagan treated the dinner with humor and respect. Obama was snarky with both McCain and Romney and was criticized for it, even by obvious supporters. I thought Mr. Trump might go in that direction as well. I am sorry he gave in to his inner snark.
It wasn’t snark. It was carefully planned. If he hadn’t gone over the edge for this event, it wouldn’t have been news.
Also he gave the impression, to me anyway, that he considers matters to be too grave for a joking, fun evening. This is serious, people, our last chance, has been his mantra all along.
