The Hobby Hour



Why Parties?

Renowned political scientist John H. Aldrich will explain the foundations of the American party system, how and why parties evolve, and the place of the two-party system in an effective democracy. Aldrich’s examination of the profound changes in political parties since World War II and the driving forces behind the increase in polarization has prompted conversations around how the political divide affects governance today.
