This simply tells me that you're not truly serious about Bernie's causes. Because if you were, you wouldn't be so glib about sentencing it to death via GOP judiciary.
Say we elect Bernie 2.0 in 4 years. In the meantime, RBG has been replaced by a Scalia clone.
The moment the ink dries on any progressive legislation that Bernie signs, a challenge is filed in court. Ruling, appeal, ruling, appeal, SCOTUS essentially exercises a veto.
Thus far, I've only seen: "we can pack the courts!" and "we can lobby SCOTUS on really big cases!" You have no real counter to this.
