Luigi Zingales, writing for the NYT:
Mr. Berlusconi was able to govern Italy for as long as he did mostly thanks to the incompetence of his opposition. It was so rabidly obsessed with his personality that any substantive political debate disappeared; it focused only on personal attacks, the effect of which was to increase Mr. Berlusconi’s popularity. His secret was an ability to set off a Pavlovian reaction among his leftist opponents, which engendered instantaneous sympathy in most moderate voters. Mr. Trump is no different.
Perfectly applies this very morning. Twitter is full of people talking about Mike Pence getting booed by the audience at Hamilton last night. Now Trump himself is tweeting about it, focusing news media on the incident. Booing is not meaningful opposition. But it has served to distract from a legitimate scandal: Trump settling a fraud lawsuit for $25 million yesterday. The smart opposition is focused on that today.
