You are right on target.
The case involved a woman using marijuana grown in her home for medical purposes. Anyone who supports federal prosecution of such an act is not a conservative, nor do they understand or support liberty. I don't what's more jaw dropping; that the 'enlightened' progressives on the court supported the government's position, or that Scalia agreed with them.
It just provides further proof that Scalia substitutes his moral judgments in place of bedrock constitutional principles.
I’m sure the court liberals were sympathetic to her plight but their leftist agenda requires them to support a perverted and vastly expanded notion of interstate commerce. If Raich had prevailed, that could have led to the Court striking down the entire Controlled Substances Act, which would have horrified liberals and so-called conservatives alike.
