First, Lester Holt did not do the best of jobs on the one thing a moderator is supposed to do — control the allocation of time and prevent the candidates from talking over each other — but he did the right thing in mostly letting them talk and let the voters see them for who they are.
Second, both candidates showed up as . . . themselves. Trump filibustered and blustered and attacked Hillary from the left as well as the right; Hillary went for the wonkish support and the prepared, canned answers, the low-hanging fruit on sexism, and the adult answers on foreign policy that sounded like George W. Bush but ignored the actual facts of the Obama years. As I noted earlier, what Hillary very obviously did not do was to try to explain why Trump is not a normal Republican — yet she also did not really try to hang him around the necks of down-ticket Republicans. Both sides ignored the down-ticket, party-building types of answers.
