I think that's about step 1... if the republicans were gone... more democrats would be challanged from the left. Either a real left wing party could be established. Or democrats would be able to consistantly be forced in the right direction. The biggest problem is the constant if we don't 100% unify quickly we risk the facists taking over and creating messes that will take 10 years of good policy to reverse even if we get a perfect candidate in, is the giant problem.
