yes, but this is nothing new. Reagan was basically cognitively absent in a significant portion of his last term, and many believe his wife essentially took the role of the presidency. This has been talking point among democrats for decades now, so there was a lot of "revenge" coping going on with Biden. His cognitive state is not truly known. The books, like Tappers, have provable false information them. However those within the west wing at that time have things against their stated evaluation on Biden's competency. We, unfortunately, have no idea how bad it was, and all the outpouring of statements against him, and in his defense, are too full of intentional disinformation to really know, at this point. I imagine that some years from now there will be information that comes to light that cuts through a lot of this obfuscation, and we will have closer answers. Right now too many parties have interest in it being not known. I think if there was clear records of his decline in the records from the white house, Trump would be parading them around. So we shall see.
