Summary: Steven Levitsky is professor of government at Harvard University. He has spent most of his life studying Latin American politics and history, with a focus on political parties, authoritarianism and democratization. He is co-author of a book called "How Democracies Die." Here, Steven and I discuss what he means when he calls political parties the "gatekeepers of democracy," and why the Democrats reduction of superdelegates in their presidential primary may have unintended negative consequences.
