my suggestion is to recognize that we are past the point of reconciliation and accept that separation is needed. Separation without violence is possible by allowing people to choose. I suggest a vote at the county level to affiliate with the New Republic or to remain with the current state. A vote confers the consent of the governed. A vote at the county (or similar) level avoids disenfranchisement by gerrymandering. The remaining issue will be dealing with the isolated areas. I believe that the majority of those will be major urban areas and the options are to affiliate with the New Republic or to form a confederation of city-states as in ancient Greece. Allow people a reasonable time to clear up personal affairs and move without penalty. We will also need to renegotiate agreements and negotiate treaties....eg water rights. Obviously a huge heavy lift, but the intent is to allow people to live as they choose without the threat of violence to resolve our differences.
