In a world where the "pussy grabber" got elected how could these accusations be said to end Biden's bid? It might lead to his not running, but I doubt we're there yet..
The practical political issue is that giving Biden a pass on this plays straight into Trump's hands. Since the "pussy grabber" got elected he's been screaming about liberal lies, and his base believes every word. If touchy Joe gets the nomination we'll hear every day about how the liberals faked outrage about his pussy grabbing, which according to him, never happened and was another lie and everything they say about him is also a lie. And his base will believe it, because the left has made it true. All Joe really needs to do is say, "Donald, you have conducted yourself with such unbelievable crudeness and vulgarity not only during your presidency and campaign, but over your entire career, that it doesn't remotely compare. Do you know what 'remotely' means?
Having said that, it seems Biden still sees nothing wrong with this conduct, which at best is patronizing. He's been the guy at the top, comforting and bestowing his own wonderfulness on the little ladies. And he thinks that's great. My guess is there is no footage of Biden doing this to a woman who clearly outranks him. It's possible that Biden could fix this. It all depends on what he says. And, of course, on him ceasing to lay hands on women who haven't issued an invitation. Biden needs to do something that may not be possible for him: he needs to stop thinking of women as fair flowers who will be grateful for his touch.
Obviously he's not a pedophile. He either has no idea he's crossing boundaries considering how often people have called him on it over several decades or he's unable or unwilling to control his behavior even after myriad people have told him and articles have been written, and bits on tv shows have been aired and social media comments have mounted into the thousands over his behavior and that's not someone with good judgment and/or ability to control his impulses. Just like our current President, but he is somehow untouchable.
