Examples
When the feds tried to ban my state's legal weed, we dusted off the 10th Amendment like an old vinyl record at a rave.
The 10th Amendment is basically the Constitution's polite 'not my circus, not my monkeys' to overreaching bureaucrats.
States' rights fans treat the 10th Amendment like a superpower cape in battles over everything from guns to craft beer laws.
Invoking the 10th Amendment is the political equivalent of ghosting your nosy neighbor who wants to control your thermostat.
