Welcome back to TPI’s Podcast Two Think Minimum. It's Monday, October 29th, 2018. We're excited to talk with Patrick Warren, who has a Ph.D. in economics from MIT and is now an Associate Professor of Economics at Clemson University. Patrick has become a leading authority on the impact of Internet trolls on elections, which is obviously of huge importance as we head into the midterms. His work is based on a data set of about 3 million troll tweets that he and his coauthor Darren Linvill downloaded and have made available to everyone via the FiveThirtyEight website. We'll talk about this and more on today's podcast.
