And he likes to reach across the divide to make the lefties happy on occasion.
Look for Roberts to become even less Conservative at a higher rate than his current trajectory.
Roberts is compromised. I am convinced they have something big on him. He was going against the ACA and did so in the test vote. The Rat judges tipped off Obongo and they went to work. He totally reversed course and even found a way to save it. He also screwed AZ when they tried to enforce the immigration laws. Both of these damaged the nation beyond calculation.
That is because including justices from say, 1900 on, would show how insanely leftist the court became after FDR.
I expect the way the jusitices were graded was based on lefist definitions of "left" and "right".
Highly subjective.
