There are lots of political parties in the United States - so how come we pretty much only hear about two? What is the 'two-party system' and why does it hold sway? Is it an intentional part of governmental design, or is this simply how history shook out? In this episode, we'll explore those questions, hear from an original member of a third party, and dig into something called Duverger's Law - which explains why two parties tend to dominate in American politics.  Our guest is Civics 101 Senior Producer Taylor Quimby. This episode also features Hans Noel, political scientist at Georgetown University, and Lenny Brody, a member of the steering comittee at The Justice Party.
