I'm not sure how the Kavanaugh thing should have been handled. Maybe the next name on the list, or a full investigation, but she chose to not keep pursuing charges. If she didn't stop, then yeah, he should have been benched.
Mueller is a whole 'nother rabbit hole on his own. After watching him lie and lead us into Iraq under false pretenses, I wouldn't trust anything he says. I have no idea how he's even still employed in some of the highest offices in the land. It's crazy that he got picked for something as important as the Russia investigation.
It was a last ditch effort to derail a nominee. There's no question about that. I mean, yeah, sure, if it was a legit claim it should have been pursued before the nomination proceedings started. The Mueller claim deserves 100% the same treatment or it exposes that there's politicization of sexual assault claims. How many times does this have to happen before that is stopped? In the last two years, off the top of my head, Roy Moore, Kavenaugh, and Mueller. Only one of those serve the democrats and only one is being dismissed. This is why I'm all for pulling Mueller out of the Russia stuff until there's a full investigation or the whole #BelieveAllWomen thing is a fraud and completely undermines women's credibility. Nevermind anything else in Mueller's past... this is just as important as the others. The fact that it's being called a smear-job is utterly insane even if it is a smear-job.
In short, the point is to show the world what a political circus sexual assault claims have become. And it's working because no one on the left is really talking about it and republicans will remind democrats and they'll be completely justified.
And, just like Kavenaugh, he should be declared unfit until the investigation is over and all the Russia investigation materials should be sealed until the investigation is over.
