Well perhaps before, during, or after the Civil War it may have happened. But I mean that was a different political atmosphere back then. A lot of strange things happened. Today if the Democrat has their nominee after Super Tuesday, they will start their national campaign and we wont even have a nominee yet. Thats going to be devastating.
As for Florida...remember it’s winner take all. Whoever is #1 gets all 57 delegates (perhaps 114 if the convention decides to seat all of Florida’s delegates).
#2 gets zero delegates. That’s why Huckabee is pulling out of Florida. He has little chance of finishing first.
