ABC News: “With days to go the debate, Trump has carried out conflicting and confounding strategies both repeatedly targeting Biden’s mental acuity, claiming at a recent rally he doesn’t know he’s alive, while also making passing attempts to boost the former vice president as a seasoned debater who could outshine him. “‘This guy doesn’t have a clue. He doesn’t know where the hell he is,’ Trump told his supporters in Pittsburgh a week to the day before the first debate. ‘This guy doesn’t know he’s alive.'”
“At a campaign rally Saturday night in Pennsylvania, the president both attacked Biden as ‘dumb’ before immediately lauding him as an experienced debater. ‘He’s a dumb guy. Always known as a dumb guy. But we look forward to seeing him in the debate. He’s got a lot more experience. He’s got 47 years. I’ve got 3 1/2 years. So we’ll see. But he’s got 47 years of experience.'”
