That was before Justice Kavanah replaced Kennedy. It’s a different court now. And in a year or two there could be one of two more Trump justices. Don’t be so defeatest.
Being realistic isn't defeatist, and denying reality isn't going to restore our rights. SCOTUS voted 7-2 to reject writ of certiorari for Peruta v CA. So now we get defeated 6-3? Not really helpful. And, SCOTUS has denied certiorari in another 2A case since Kavanaugh joined the court, and specifically denied cert on a magazine capacity case from the 4th Circuit in 2017. For the moment, it is likely best that we do NOT argue these cases in front of SCOTUS, as we may not like the result. Just one of the many reasons it is critical that we do not lose the WH or Senate in 2020. Replace RBG with a justice who respects the constitution and we can start celebrating.
SCOTUS is deciding it's first 2A case since Heller this session in Mance v. Whitaker. Not a case that will have wide impact, but at least we will get a feel for where we are.
