Could be. My wife who is a retired nurse who specialized in dementia care, believes his behavior is consistent with Korsakoff Syndrome which is most frequently associated with heavy drinking but not always... Biden gave up drinking long ago. He claimed that there were enough alcoholics in his family.
Biden has also claimed for years that his first wife and daughter were killed by a drunk truck driver. In reality the Senator's wife ran a stop sign. The truck driver swerved and turned his truck over trying to avoid the collision. The driver climbed out of his over turned truck and was the first to render assistance. A thorough investigation found that the truck driver was not at fault in any way and had not been drinking; no charges were ever filed. The poor guy was reportedly haunted by the accident for the rest of his life and his family said that they are fed up with Joe Biden constantly smearing the poor guy.
“his family said that they are fed up with Joe Biden constantly smearing the poor guy.”
If they were decent, they’d be out there spilling their guts and spreading the truth.
(BTW, I had heard/read that Biden Wife #1 had alcohol in her system when the accident occurred.)
