Even if you take EVERYTHING Biden has ever done or accused of when it comes to women there is no ceding the "Moral High Ground" to Trump and the GOP. I dont care if Biden rubbed the shoulders and smelled the hair of every women in DC since he got there it doesnt even move the needle compared to the antics of the GOP in the same time. There is no "Moral High Ground" to lose because the GOP stopped caring about that long ago. They know their voters dont care...and they know a high percentage of the voters in general dont either.
This is not the fight to fight. This is cutting off your nose to spite your face. You keep going after him for stuff like this it will backfire I promise you. Why do you think his numbers are still friggin good despite all sorts of Biden Stupidity? Because the vast majority of people dont care if he an old dude makes old dude comments and acts like a creepy old dude.
Look we both want the same thing (Biden to Lose) so let it happen organically. Dont turn him in to a sympathetic figure by going after him every 12 seconds because he sounds like an idiot when he opens his mouth. Let the candidates do that when they face him at debates. That is the only thing that has dented his armor, Harris going after him. That is the way to beat him.
