I expect Roberts will return to voting Constitutionally once he is no longer the deciding vote and his blackmailers can’t use him any more. Expect a lot of 6-3 losses for Big Leftism coming up.
Not if it wasn’t blackmail that caused him to flip. Maybe he was a lib all along but hid it until he got his SCOTUS seat... or maybe he was bribed, in which case the money may not stop.
