Let me get this straight.....
you think each State should be allowed to decide for itself? That the Feds have no business sticking their nose in this?
Well then......... realize that O'Connor, Thomas and Rhenquist were the ONLY dissenters.
The "liberal" SC judges, John Paul Stevens, David H. Souter, Ruth Bader Ginsburg and Stephen G. Breyer all voted give the FEDS the power to decide, not the States.
Kennedy and Scalia, normally "states rights" types, sided with the "liberal judges" this time. Scalia wrote a separate opinion to say he agreed with the result, though not the majority's reasoning.
Looks like your activist judges were the power behind this move to take away the powers of the State to decide "medical marijuana".
