Hell no I am not. Roberts was a real shock on the ACA. They can happen. But the Roberts court is the worst for workers and pro corporation of all time. Their decisions are extremely predictable.
The Federal Society was developed for this purpose. It is not an accident. They are designed top push right wing conservatives in important positions, especially the courts.
They are only predictable on certain types of cases. On many different types of cases their votes vary. Souther, appointed by Bush, voted with the liberal bloc. And, of course, many prior Republican appointees did not always vote conservative--Warren, Kennedy, Blackmum, Stevens. Roberts has been attacked by other conservative organizations because he has been left of Thomas, Scalia, and Alito.
Do you think liberal groups seek to have liberals placed on the court? That makes them like the Federalist Society and other political interest groups in America.
