Why so much outrage about Tuesday’s debate? Was someone expecting a sensible discourse on policy? Really? Moderator Chris Wallace expressed his own surprise. “I never dreamt it would go off the tracks the way it did.” How could he have forgotten all the staking and name-calling in the Clinton/Trump debates?

No matter what the format, no matter what the rules, Trump will insult, badger and bully. That’s what he does. (“Don’t ever use that word smart with me. Don’t ever use that word.”) His strategy is clear: put a phrase on repeat – “far left radicals”, ” three and a half million dollars”, “Antifa” – like an angry Alzheimer’s patient.

In other words, it isn’t hard for Biden to beat Trump with words. All he has to do is shake his head at Trump and deliver a zinger or two. Not “clown” or “shut up”, but “Behave, Donald” or “Your wall is a swamp.” Trump’s racist rants will do the rest.
