Your response only makes sense if the there are no constitutionally enforced limits on the powers of the federal government vs. state governments. The Medicare portion of the ACA being struck down by the Supreme Court is a notable counterexample to your comment. The check on federal powers may not go as far as you like but laughing in response to the comment that was made is in poor taste.

Except that, AFAICT, didn't happen. (Though there is a current challenge to the Constitutionality of the Medicare changes, among other things.)

You may be thinking of the mandatory (for continued state participation in Medicaid) expansion of Medicaid portion of the ACA being made optional rather than mandatory by the Supreme Court.

Of course, one could argue that is an example that is arbitrary and, while it certainly evidences judicial limits, is hard to connect to it's Constitutional pretext, as it explicitly requires that both pre-expansion Medicaid are post-expansion Medicaid are Constitutional federal programs, but that Congress is somehow barred from replacing one with the others except by consent of the individual participating state.

I didn't mean any disrespect, but fair enough. Edited my original comment.
