I think that the people who ignored or yelled at those who pointed out that A LOT of voters thought Biden was too old for another term should do some self-reflection but I don't think they will have the humility to do so.
To be honest, while I feel vindicated from after I got bullied last year and this year for mentioning Biden's old age was going to catch up with him at some point and that he couldn't outrun it forever, though I suddenly am wishing I was wrong and they were right, this just sucks to be right about.
