Giving liberals a few states to call their own country might be the solution to our, and their, problems. They could elect Obama as president for life, call their paradise New Venezuela, import all the radical Muslims they want, eliminate all fossil fuel usage, place NAMBLA in charge of the schools, ban guns, ban Christianity, ban offensive speech, and provide everyone with free homes, free cars, free food, free education, free health care, free sex change operations, and $100 per hour minimum wages. I’m sure people would be flocking there like black Friday shoppers.
NO! Nay! Never!
You cannot trade land for peace. The violent and evil will just use the land you "gave them" as a base of operations to make war against you and attempt to acquire more land.
Ask Israel.
The Israelis know all about it.
That said, the vast majority of Americans, left and right, and fat dumb and happy. They would no more consider a division, civil war, or split of any kind any more than they would consider living on Mars...I.e., a theoretical possibility in the seemingly near future if it crosses their minds, but not something they think about 99% of the time.
I don't foresee any kind of division either. The US will just slowly turn into Venezuela while we grumble a bit and that will be that.
