Your observation was spot on.
For many years I myself have considered the decline in conservative intellectualism to the dumbing down effects of FuxNews and the rest of the rightwing media. Certainly Trump got sucked into that mass mental delusion. But this is something more than what I thought. These are clear signs of dementia, not just forgetfulness. A diseased brain to go along with the already narcissitic, egomanical, megalomaniac mental illness.
