Not Another Politics Podcast

While we take a quick summer break, we wanted to re-release an episode that felt timely, given the rise of right-wing populism around the world. More than 25 percent of countries around the world are currently governed by populists, from Recep Tayyip Erdogan in Turkey, to Donald Trump in the United States. Based on these findings, populism is at an all-time high, and taking a significant economic toll, according to a recent paper by Christoph Trebesch and his co-authors.

Trebesch is Professor of Economics at Kiel University. He and his co-authors find that populism leads to slower economic growth, undermines democratic institutions, and can leave the country more vulnerable to future populist governments.

Since the fall of Roe v. Wade, we've been told a simple story: red states are radically out of step with public opinion. But what if that's not actually the reality? On this episode, we speak with Natalie Hernandez, Yale PhD candidate in Political Science, about her upcoming APSR paper, "Asymmetric Representation: Post-Roe Abortion Policy and Public Opinion in the U.S. States." Using a massive dataset of 155,000 respondents, Hernandez finds policies in Democratic-controlled states are actually furthest from the average voter, and what happens when Democratic lawmakers prioritize wealthy donors and national activists over the median citizen.

In this episode, we speak with Victoria Barone, Assistant Professor at the University of Notre Dame, to discuss her recent NBER paper that examines the possible relationship between the opioid epidemic and the political realignment between the Republican and Democratic parties.

While the public health consequences of the crisis are well-documented, Barone’s research uncovers a startling political fallout. We explore how the rise in opioid-related deaths and addiction has altered voting patterns, shifted party leanings, and influenced electoral outcomes in the hardest-hit communities.

In debates about the Supreme Court, we tend to focus on the justice who writes the opinion. But what if that’s not where the real power lies?

In this episode, we speak to Jonathan P. Kastellec, Professor at Princeton University, about his new paper that challenges how we think about decision-making on the Court. Instead of opinion authors driving the law, Kastellec argues that power often rests with the median justice within the majority coalition—the key vote needed to hold five justices together. So how does bargaining actually work behind the scenes? Why do some precedents erode gradually while others collapse all at once? And what does this tell us about major decisions—from long-standing rulings to sudden reversals?

We're off this week for a much-needed spring break, but we wanted to re-share this episode that feels more relevant than ever. Infrastructure in the U.S. now costs dramatically more than in countries like Germany or Croatia—without clear signs of higher quality or better environmental outcomes. Why has infrastructure spending spiraled out of control? Could democracy itself—through litigation, regulations, and empowered citizen voices—be driving costs sky-high?

George Washington University Professor of Public Policy Leah Brooks investigates why the U.S. pays so much more per mile of highway compared to other nations in her paper “Infrastructure Costs”. Brooks reveals shocking findings: from the late 1960s onward, the cost to build highways in America surged dramatically, not because of higher wages or materials, but because of legal battles, environmental reviews, and citizen demands.
