That a thousand time.I agree, and one such gaffe would be to do anything with respect to the claims relating to the laptop/hard drive than simply laugh them off.
A more eloquent person than Biden maybe could make some joke about the "cancel Christmas" idiocy and the "Christmas at the Bidens" picture the NYP published.
But as you say, Biden should really just laugh it off. The "base" will see it as further proof he is a paedophile eating puppy-pizzas for breakfast, but Biden doesn't care about them.
