The video the other day when “he was not supposed to answer questions” was more evidence of his mental difficulties.
He could not remember the name of the House minority leader, Kevin McCarthy. He struggled with it for a few seconds and then just referred to him as “the house minority leader”.
He also couldn't remember Benjamin Netanyahu's name and after verbally stumbling for 3-5 seconds finally said "the prime minister (of Israel)"
Those of us who have family members that had and died of Dementia / Alzheimers recognize the decline in Biden. All we had to do was watch him for 10-15 minutes during the Democrat debates to see how far he'd declined since 2016.
Biden's always been a bumbling idiot but the difference between then and now is striking.
