I think we need to apply Occam’s Razor here.
Either Roberts’ decision was some sort of super-complex piece of 10-dimensional chess that he was playing while making the pieces move with his mind.
Or Roberts’ decision was simply another example of a typical method by which our government has been granting itself exemptions from constitutional and other limitations for over a century.
I’m thinking it’s the latter.
It’s the latter I think too. Its as simple as this - Roberts was cowed by Obama’s threats. Period.
