The gullible Right emerges. Energized by Biden's obvious frailty. Now a stolen diary written by a distraught daughter who went through a very hard spell of life and wrote things off the cuff are proof positive that Biden is a pedophile. In spite of said daughter absolutely denying the accusation; in spite of zero evidence other than some cobbled together amplifications/intentional misinterpretations of fact.
I concede that the passage in Ashley Biden's diary where she scribbled a brief sentence about "probably not appropriate" showers while in a clearly confused state of mind seems to be authentic. Given her state of mind when writing this passage it comes across as more of a stream of conscious wondering from a likely intoxicated mind, rather than an accusation against her father.
Let's say, for example, that Biden is actually a pedophile. Then why isn't the diary full of passages about Biden's molestation? Where are the other children whom a true pedophile would molest? Why hasn't Ashley Biden now, or in the past, ever leveled accusations of pedophila against her father? What about Jill Biden? If a mother thought that her husband was sexually molesting her daughter, 99.9% of them would demand divorce and seek full custody.
The accusations about Biden being "a pedophile" and "not a nice guy" are total bullshit - it's the Right's politicization of events, warping the narrative to bring down a democrat.
Meanwhile, their convicted felon with actual documented, proven evidence, court records included, is somehow not to be condemned. The guy had sex with a prostitute while married; and paid hush money to her during an election campaign in order to keep her quiet; and then lied about the expenses. Numerous other court cases against their guy are underway, including mishandling of classified documents and promoting sedition- but no, all of this is conspiracy.
TL/DR - Biden's extremely poor performance in the debate energizes and emboldens the MAGA Right to make further completely unfounded attacks on Biden. And Joe's performance in the debate is so depressing to the Left, that the tendency is to give in to despondency - a mindset which results in lack of enthusiasm to push back against ridiculous claims by the MAGA Right.
FWIW - I think that BIden is old, but would be competent as president. I'm not sure if he'd live out his next term, but if he were to pass away while in office, Harris would assume power and I've every confidence in her ability to govern. Meanwhile, there's no recovering from Biden's debate debacle no matter how hard he tries. Any slight slip, however innocent, will be jumped on by the Right to insist that Biden is incompetent. Any major gaff would be far worse - and I suspect that Biden has several major gaffs in store should he continue to run.
