Huh?” Roberts is Kennedy’s replacement. “
He means that Kennedy was the swing justice, the 5th vote if the Democrats are going to win on an issue . . . and now that is Roberts. Were RBG to leave the bench, it’s far from clear who would be considered “the swing vote,” since it would take Roberts (in the poster’s telling) and then a fifth vote on top of that. And victories for the anti-constitutionalists would become much less frequent.
Thanks for the explanation, I didn’t feel like clarifying the obvious. I don’t trust Roberts to hold with the Constitution. My opinion, I’ll hold with it and watch the court.
