Horsehockey. What we have seen is that certain justices will vote in whatever manner they deem fit to push their own agenda, precedent be damned, with the classic example being the inherent contradictions, just a few months apart, between Raich and Gonzales, as noted by Clarence Thomas in his dissent in Gonzales.
My daughter was in a small college seminar group with Roberts a few years ago. He said that his general philosophy is to leave decisions to the people in the decisions made by their elected representatives, since, in his opinion, it is much easier to change the Congress than it is to change the members of the Court. I guess this ruling was consistent with that. However, it is totally divorced from the reality of my entire life due to its ignoring of the heavy propagandizing involvement of our MSM. They are even now allowing the administration to get away with morphing the basis from taxing power back to a mandate, despite the explicit rejection of that. Opponents can’t let that happen. “Taxation by Misrepresentation” needs to be reinforced early and often , like “It’s the economy , stupid” was in 1992.
