Depending on how long the war went on, the Democrats would gain an advantage, since we have the scientists and Harvard grads that the GOP doesn't. We also have an escape route, the right doesn't. I know I would fight for my side, and I'm confident in our victory.
Harvard grads matter little when it comes to expertise with weapons. I don't know that technology (in terms of mass destruction) would matter with any future civil war. If it did, the "red states" would have a loss less concern for the fate of cities than "blue staters" would have for open spaces and the environment.
