It is disingenuous for the Party leadership to call for unity when they have already betrayed that principle themselves. So, I would prefer to clean house and let the PEOPLE, the would in this case be registered Republicans, call the shots.
Do you have a problem with that?
Unity is not an end unto itself. (Germany in the 30's was unified around nazism.) The question is: Unify around what?
Unity is always the first desire of those in power. Always.
