One of Biden's secret weapons has been his opponents cocooning themselves in internet bubbles of his gaffe clips and convincing themselves that he has dementia, which enables him to easily beat expectations when normal voters see him speak and realize that's not true.

I don't really get how this idea that Biden is senile and can't talk is going to survive contact with reality. He used to be a great, world-class talker, still pretty good.
