The problem is that the stratified cultures that form the arbitrary two sided political dichotomies (see Britain for another great example - given current norms it would make perfectly good sense for Scotland, London, and Northern Ireland to secede from the more conservative England and Wales). But they are arbitrary. The talk radio in the rural conservative parts and the Internet circlejerks in the liberal ones have divided peoples way worse than they were a hundred years ago by putting the soft-reds and soft-blues into echo chambers of the most ardent idealogues and turning many into adherents that place their personal identity into their politics. The other problem is those of us guilty of that - the framing of our identity on high-brow concepts like ideology - don't want to change. Who wants to revert back to ignorance on how you personally think the world is best ordered? The rift will only grow until dissolution does happen unless all participants admit that they want to preserve solidarity in society. They will not be able to change themselves, but they can train future generations to not base themselves so heavily in politics such that they do not segregate themselves such. But it would take everyone agreeing on something nobody wants to have happen. So... yeah right.
