Actually, all the Civil War did was codify the Union's violation of State's Rights. In the Federalist Papers, the concept of secession was understood as implied by the Founders. It wasn't until AFTER the Civil War that the SCOTUS altered the rules to require states to get the POTUS' permission to secede.
IMO, given the politically divisive environment in America today, when the clash comes, it won't matter if we have a secession approved by the POTUS or an out and out revolt; the desire to not be bound by or live under the oppressive Obama regulations is in the air. And I believe that that desire to "fix" the problems associated with Obama will grow more intense after Taxmageddon kicks in.
The Feds are about to implode, Beghazi, Hostess, Denny’s, Papa Johns.
Look at all the individual items all connected to Obama.Unions screwing America, Busniness charging Obamacare surchases, mass layoffs and the loss of full time work weeks.
All of it can be traced directly back to the infiltration of America by the Muslim Brotherhood and the Communist Party USA, and the figurehead Obama .
