Kavanaugh is accused of inappropriate contact a bunch of years ago; there's zero evidence, practically no testimony, no way to prosecute, and delaying doesn't really make sense either unless they can delay it through the election and then some. So maybe there's another motive?

For instance, look at this allegation that Rod Rosenstein was planning to wear a wire in conversations with Trump, and was attempting a soft coup. It's probably not actionable in court, I don't know if actual evidence of him trying such a thing exists. Still, Trump could fire him on this basis and probably should. But what if this is intended to create a false equivalence, to accuse Trump of being a hypocrite and keep Deep Staters in place?
