For all the journalists in the world who have run out of words to describe Donald Trump, a bit of good news this week: He’s run out of words, too. Because what his re-election launch in Orlando on Tuesday night before 20,000 of his most enthusiastic fans packed into the Amway Center most resembled was one of those “greatest hits” tours by a fading performer who is sticking to his old material. It may be familiar. It may be worn. And, in this case, it may be highly misleading. But, hey, everyone knows the lyrics and when to applaud.
