It has a chance if we all work from the same first principles. For example: Reasonable people can disagree. If we agree on that principle then ad hominem takes a hike and compromise is possible. A democracy without compromise is a democracy on the edge of failure, IMO. And I would submit to you taht it doesn't matter which side we may find ourselves on. The net result is failure of liberal democracy.

American politics is become increasingly similar to the Cold War, in wich the sides struggle for supremacy at every juncture, never ceding ground for fear of losing the war. But the difference (thus far) is that the game doesn't end. There is another election and the rules shift. Unless both sides that intransigent cold war is better than compromise. That is where we are. In my opinion, that is why most parties must die an undignified wholly partisan, ignoble popular death. I see nobody of stature in either party willing to risk the the ire of their fellow party members to cross the barrier. Cowards.
