The stories aren’t true but I don’t think he’s lying. I think he’s non compos mentis.
Biden has a psychiatric syndrome called “pseudologia fantastica.” It is seen primarily among long term character disorders— a pattern of self-aggrandizing and extremely hard to believe fictions which the patient seems sincerely to believe despite many of them being essentially impossible, or contradicted by plain evidence to the contrary. In Biden’s case these predate his onset of dementia, which can exacerbate the symptoms. Together with his documented history of plagiarism, cheating in law school, violation of sexual boundaries with minors as well as adult victims, the potential for a formal diagnosis of antisocial character is reasonable.
non compos mentis? Don’t give him that benefit. The guy has been lying for a loooong time. Unless of course you’re claiming his diminished mental capacity goes back many years. He lied about his ranking in law school many years ago. 1987……. https://www.motherjones.com/politics/2019/05/that-time-joe-biden-lied-about-his-academic-credentials/
