I mean surely he has taken the stages a bazillion times before and spoken in front of huge crowds for decades. How could he get the yips and go stone cold at such a crucial time?
Ever freeze anywhere for any reason? Some folks freeze in test situations but they know the work. They just can't connect to it for whatever reason.
That is not a good trait in someone who is supposed to lead a country and be swift on his feet at all times. What if he were to freeze at an inopportune time? What then? Could it be a vestige of senility come home to roost? Seriously. His performance was shocking to me of all of them. Mentally undependable is not good.
