If President Joe Biden’s disorderly and lethal Afghanistan withdrawal was the moment that fractured voters’ regard for him, then his vicious Atlanta speech last week may be the moment that defines his presidency.

Speaking Tuesday at Morehouse College and Clark Atlanta University, Biden uttered venomous, brutal accusations lacking factual basis. His shouting-in-the-wind delivery was inexplicable, and his decision to lash out at members of his own party — Sens. Joe Manchin and Kyrsten Sinema — appears to have only strengthened their resolve not to give in to his demands.
