It’s tough to know how to adequately sum him up. So, let me try a local example. You know that horrible thing currently clogging up the London sewers, I believe you call it the “fatberg?” Well, Trump—he’s the political equivalent of that: a merger of all that is noxious in the culture, economy, and body politic, all kind of glommed together in a self-adhesive mass. And we’re finding it very, very hard to dislodge. It gets so grim that we have to laugh. But make no mistake: whether it’s climate change or the nuclear threat, Trump represents a crisis that could echo through geologic time.
