Exactly! What the Constitution /says/ and how it is interpreted... The Tenth Amendment is written (IMO) incredibly short to underscore its importance AND breadth:

"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."

But I've very seldom heard the phrase "states rights" uttered by anyone who isn't pro-gun and anti-abortion. I doubt they'd feel any freer if their state came down like a ton of politically-angered bricks on unfettered gun ownerships and anti-abortionists.
