Democrats should have looked for a Biden replacement a year ago; the plan should have been to bring fresher blood in to succeed him. Huge oversight on their end, and now they will probably pay big time for it.
It's no insult to Biden that he has lost some cognitive function, this happens to people as they get old. He's not "demented" or "senile", but he's definitely not as sharp. There is no point in making excuses for it. Trump is a horrible person and a horrible candidate, but optics matter more to a large chunk of our braindead population. That's the reality of the situation.
Exactly this.
