If it helps, I think there is a good chance they will grow out of this. The tide of history has changed. I do not believe that any intelligent person can watch freedom and democracy and peace spread around the planet without wondering "Why does my side always lose? Why does life get better in those parts of the world where my side loses? Could my side be wrong?"
As a historian, this makes me sick. But these people are the FEDERALISTS of the 21st century---out of power, and rapidly disintegrating into oblivion. I honestly won't be surprised if within 10 years there is no longer a Democratic Party as we know it. It's getting that close. Now, that's not all good, because we need competition in our system to keep each side straight.
You would think they would have learned their lesson after the Berlin Wall came down. The left is now on their third crack at the apple.
