I agree with you up until the last paragraph. Biden has really yet to show any signs of life. The fact that he already has to "pace himself" by doing very little, just a few months into it, when he doesn't have to go state to state like all previous candidates - this terminal lack of energy is not encouraging for him when the campaign gets going, nor as a future President.

We shall have to rely on Trump defeating himself. Luckily, that seems to be happening.
