I have read snippets of this information elsewhere, including a large article posted some time ago on FR. If you’ll read the material in the article you’ll see that it refers to events that have occurred and are about to hit the fan as far as Chief Justice Roberts is concerned.
Events that occurred mean nothing until a case is brought and winds it's way through the lower courts, and then is accepted by the USSC. Are any of these mentioned, except the obamacare mandate, even on the USSC docket?
