Kavanaugh might be acting. If you want to persist on believing that, fine. But the obvious explanation is that he is acting exactly like an innocent man accused of something aborrhent on no basis but a partisan individual's assertion under suspect circumstances, would act. Just because he's not doing what you want does not make his behavior suspicious or incongruent or have an ulterior motive. "Not wanting to be known as a rapist" is generally more than enough motivation for most people.

Which just goes to show the double standard of behavior. Kavanaugh called them out for things they actually did. By your logic, judges who denounce the behavior of a defendant, or the extremity or invidious nature of his crimes, should immediately have to recuse themselves from passing sentence. He gets attacked, so the people who attack him now get a free pass forever, because their actions have rendered him incapable of objectivity? No, if you want to smear a Supreme Court Justice at the outset of his lifetime appointment, you have to live with the consequences. And they probably will try to impeach one or more justices of whom they disapprove on partisan and ideological grounds, and shriek to the high heavens about partisanship and political motivations and cheap shots when the Republicans take back the majority and impeach all of THEIR justices. Democrats always seem to think their political moment is going to last forever, and that destroying a standard for momentary political convenience can't possibly blow back on them.

So they circled the wagons around a sexual degenerate of a president and twenty years later, they're whining about Trump, while having the temerity to run Clinton's co-conspirator against him. They circulate smears about the military service of their best friend (after several years of running draft dodgers and men with truly questionable records for President) in the GOP because he's running against Obama, and then 8 years later when Trump rebuts his criticism with a dismissal of that military service and refuses to apologize for not kowtowing sufficiently to a "Gold Star family", they're appalled that he almost certainly got the military vote. They use whatever tactics are available to suppress minority opposition and brag that "elections have consequences" and rediscover the right of minority to be heard when their oponents gain the whip hand and apply the same principles and precedents to them. They spend years gloating at how many young voters get their political information from a bunch of smirking, partisan entertainers on comedy shows, and now they're appalled the GOP doubled down and elected one of their own.

And now they think they're going to try getting rid of Kavanaugh or muting him on the bench with accusations of partisanship without worrying for a minute if the GOP is going to demand the same of Ruth Ginsburg, despite her apparent public lie that she was going to leave the country if Trump won, or demand that the "Wise Latina" recuse herself on all issues of race or gender or especially immigration ever come before the court. Hell, why not force Ginsburg, Sotomayor and Kagan to recuse themselves if Roe is ever challenged? After all, they are women, and have a vested interest in the issue. Men can be relied upon to vote for or against, but no woman has ever broken ranks on the issue on the Court. Plainly they cannot be objective.
