Should we just go ahead and split the country?

My question is regarding the United States.

Should we get several states together, maybe a few out west and a few in the deep south, and let them be their own country. Or, if not their own country, have them exempt from paying federal income tax, and offer them nothing in terms of federal support? I guess they would not be able to vote in national elections. Not sure how that would work? Anyway, The idea is sort of a right wing Republican/Libertarian mindset? Maybe even a Christian focused religion in everything. It might be an interesting experiment.

What do you think about the idea? How would it work? Would it have to be two distinct countries? Would it diminish the US power in the world? Would there have to be a war to have it happen, or could it be done by vote?

Discuss.
