In Prof. Esther Robinson's "History Behind the Development of the Political Parties in the United States - Part 2", Esther picked up the story of the parties after the Civil War. She combined the historical events of the United States with how the political parties changed throughout the last 150 years. We viewed each election from 1880 and watched the demographics change every 4 years. Very interesting.
