As far as the Feds threatening to withhod Fed funds to Tenn. the people of Tenn. can withold income taxes. No more money sent to D.C. So there.
LOL - I'm not challenging you, or disagreeing with your point. But if Tennessee did that - actually did that - there would be civil war. Because the alternative would be the collapse of Federal power, and that wouldn't be accepted without, quite literally, a fight.
