LAST NIGHT was good for Kamala Harris. She won the presidential debate against Donald Trump on most people’s estimation by the simple expedient of goading him, and inevitably he rose to the bait. It was not a good spectacle for his supporters; he seemed blustering, off the point, occasionally downright eccentric. It was fair enough for him to focus on the issue of illegal immigration, the area where Harris had responsibility as vice-president, but he made the point by insisting that illegal immigrants were eating American pets, not a good idea. And he left what should have been his best point until the very last: if Harris was so anxious to change things with exciting new policies, how come she hadn’t done any of this during the three and a half years she was vice-president?
