I think America's founding fathers would be proud that the state of Pennsylvania, where independence was written, is the most crucial state to determine where the entire country will lean politically. Philadelphia, an "American Rome" is one of the most historical city in America. Both it and Allegheny are the most dense in population who lean Democrat. Pennsylvania's county can be viewed to represent the entire nation where Philadelphia represents the East Coast. Allegheny represent California who is surrounded, but not influenced, by Republican regions. In the South, Bedford and Fulton county have a strong Republican lean much like Texas. It is the Southeast and Notheast regions who get influenced the most.
