A wise man once taught me: “Nobody is completely useless; at worst he can be held up as a bad example.” It is in that spirit of hopefulness and constructive criticism that I come to praise Donald Trump (or “Drumpf”), not to bury him. Thanks to Trump, this electoral silly season has generated some of the most relevant analyses about U.S. politics, the kind of commentary that we should have started in 1980. Regardless of how one feels about Trump, his candidacy is profoundly significant.
