How could a presidential candidate turn the largest crowd of the Republican contest so far into a turnout that didn’t quite live up to expectations? That’s what Donald Trump did with his Friday night speech in Mobile, Ala.

Trump had predicted up to 40,000 people would fill Ladd-Peebles Stadium. That would have been huge, had it happened. As it was, filling about half the stadium was huge, too — extremely impressive by any standard, except Trump’s own.
