The dullest assertion you can make about Donald Trump is that he’s a narcissist who has no interest in the American people and only cares about himself. Competent pundits don’t waste wordage on such an over-obvious observation.

Less obvious, though more so since last week’s dog’s dinner presidential debate – in the aftermath of which dubbing the encounter ‘elder abuse’ went from droll witticism to exhausted cliché in a few hours – is that Joe Biden’s narcissism rivals Trump’s and may even exceed it.
