More than five hours after his rally at Madison Square Garden began, Donald Trump walked slowly on stage. The arena was filled from floor to rafters with some 20,000 supporters, bathed in red and blue light. They had listened and cheered, bought hot dogs and taken selfies as more than two dozen others spoke. A comedian called Puerto Rico a “floating island of garbage”; Elon Musk awkwardly urged early voting and happily lapped up chants of “Elon!” But the main draw was, of course, Mr Trump himself, speaking at the famous arena in America’s biggest city, in the final days of what may be his final campaign. When Mr Trump appeared, at last, the crowd roared. He basked.
