On Kavanaugh

The first two allegations were, while weak due a lack of corroborating evidence and the fact that all direct witnesses have categorically denied the existence of the events in questions (and in one case denied knowing Kavanaugh at all), at least somewhat plausible. There was a chance that such an event could have evaded the notice of the many background investigations that have been run of Kavanaugh, as unlikely as it seems. This most recent one though, accusing him of attending gang rape parties?
Brett Kavanaugh has undergone six background investigations. At least one of these was an SSBI (Single Scope Background Investigation, done for all clearances above "Secret").
This isn't some "Hey we checked a database and you don't have a criminal record". This is a "We went and talked to your old next door neighbor. And your friends growing up. And your mom. And that girl you kissed in the fifth grade. And the dude you bullied in the second grade. And your father's brother's nephew's cousin's former roommate. And he said you did weed in the sixth grade, so you don't get a clearance."
The chances that an SSBI would miss Gang Rape parties is beyond ludicrous, to the point where if the accusation is true, we've got bigger problems than who the next SCOTUS justice is.

Justice Kennedy's retirement

The current Democrat woes over SCOTUS is entirely of their own design. So far, they've had French flatulence blow up in their faces when the Biden rule got invoked to prevent Merrick Garland from sitting on SCOTUS, then again when Reid's filibuster reform got extended to SCOTUS nominations to allow Gorsuch to take a seat. Now, because it benefited them to have the Biden rule only apply to presidential elections, they're about to get another Trump appointee to SCOTUS (hopefully a strict constructionist, originalist, or textualist). It's even worse for them because Ruth Bader Ginsberg and Stephen Breyer didn't retire under Obama, when they could've at least ensured that it would only take one justice to tip the balance back in their favor. From here out, Ginsberg and Breyer have to survive until the next president takes office - two to six years from now - at an age where death can happen suddenly and without warning for a variety of reasons, in order to prevent Trump from creating a SCOTUS that would be almost impossible for any single president to flip.
I'm not exactly full of sorrow over their mistakes.

Well... Sh*t

I guess the Supreme Court simply doesn't want to hear second amendment cases, for better or worse. Having lived in California (and recently) I can say that this is distressing. Depending on where you live in CA, getting a concealed carry permit can be as easy as any shall issue state, or the next best thing to impossible. Given that California bans open carry, many residents of California are facing a de facto ban on bearing arms, a clear infringement of the second amendment. I fully endorse the dissent voiced by Justices Thomas and Gorsuch, who called the decision "indefensible".

EDIT: And I thought that they were doing, a perhaps not great job, but an acceptable one. This is rather disappointing, especially since the court still has the same number of conservatives, liberals, and swing votes as it did for the McDonald and Heller decisions.
