Cast your mind back to the Obama era, and imagine having a genuine discussion on whether a candidate has dementia, by assessing how many sentences they fumbled during their latest presser.

It’s absolutely absurd. Preposterous.

I’ve become convinced that Biden is toxic to the left. He’s got to go. Even if he is mentally competent he’s lost the faith of the left, and he’s made this campaign about his fitness rather than Trumps.

It should be a slam dunk but he’s lost it.
