One day Trump is a restrainer paring back America’s role in the world. The next, he is a true nationalist asserting his country’s domain over all he surveys. Tomorrow, he could revert to libertarianism. Today he is a pragmatic statist taking bites out of the shiniest bits of the private sector. Some make heroic attempts to depict Trump as a 21st-century reincarnation of Ronald Reagan. They get an A for effort. Like the fable of the naked emperor, he is imagined in all sorts of finery. More’s the pity that he is not playing along.
