Problem: Imagine you are an American, accustomed to (and approving of) the SMD system for electing congresspersons, and you are debating with a European who lives in a system that has always had PR. This European argues that the PR system offers chances to more political actors, saying that this enlivens debate and forces the legislature to take into account the interests of a broader range of people. Can you convince your interlocutor that the American system is preferable to the European one?
