Mark my words, if Kav gets anything less than 51 votes he'll be hounded off the court by the Rats and their willing accomplices in the press.
There's no such thing as "hounding off the court." He's confirmed, legally, and that's it. They can whine and cry all they like, and
claim that he's illegitimate, but their bogus claims don't matter. Kavanaugh himself has demonstrated rather conclusively that he is not the kind of guy to let a bunch of shrill harridans chase him away.
Frankly, if they want to try to make noise that he's somehow illegitimate despite getting a majority of votes in the Senate, they'll just be further discrediting themselves. And that works to our advantage.
