So how should Biden frame his acceptance speech? The overriding theme should be unity. It encompasses the most damaging criticism of Trump, appeals to moderates, and includes both the concerns of the left (inequality; health care; Black Lives Matter) and the right (white Christians are valued and entitled to protection, too).
Trump is bound to throw caution to the wind and give a red meat speech to his base, because it’s fun, and it’s the only thing he knows how to do. The contrast with my version of the Biden speech would be overwhelming. Given a stark choice between an arsonist and a fireman under the present circumstances, I have no doubt which way the mop will flop.
