Fish writes and comments extensively on international affairs and the rising challenges to democracy in the United States and around the world. He is a commentator in the media, including BBC World News, CNN,[8] and other major networks, and has published in The New York Times[9], The Washington Post[10], Los Angeles Times[11], The American Interest[12], The Daily Beast[13], Slate,[14] and Foreign Policy[15].
Fish's most recent book, Comeback: Routing Trumpism, Reclaiming the Nation, and Restoring Democracy’s Edge (2024),[16] examines the causes of democracy’s current crisis in America and proposes a new approach to campaign messaging for Democrats.[17]
In Are Muslims Distinctive? A Look at the Evidence (2011),[18] Fish tests a range of notions about Muslims and their political orientations.[19] He finds little support for many prevailing stereotypes,[20] including the view that Muslims are committed to fusing religious and political authority and are more prone to violence.[21] He also finds that homicide rates and class-based inequalities are generally lower in predominantly Muslim societies.[22]
Fish’s work also includes research on legislatures and their role in democratic governance. His coauthored book, The Handbook of National Legislatures (2009),[23] measures the powers of the national legislature in every country in the world.[24] He served as the Project Manager for the Legislatures section of the Varieties of Democracy (V-Dem) project. In an article, “Stronger Legislatures, Stronger Democracies” (2006) he argued that vesting substantial power in national legislatures is vital to sustaining democratic regimes.[25]
In Democracy Derailed in Russia: The Failure of Open Politics (2005),[26] Fish investigated the demise of Russia’s democratic experiment in the 21st century.[27][28] He argued that Russian democrats’ failure to build a strong civil society, along with flaws in their economic reform program, Russia’s hydrocarbons-based economy, and the country’s “superpresidential” constitution paved the way for the resurrection of autocracy under Vladimir Putin.[29]
Fish’s earlier work focused on Russia’s democratization after the dissolution of the Soviet Union. In Democracy from Scratch: Opposition and Regime in the New Russian Revolution (1995),[30] which was based on two years of fieldwork in Russia during the late 1980s and early 1990s,[31] Fish argued that Russia’s democratic breakthrough, while momentous and impressive, might prove short-lived given the lack of emergence of a realm of robust civil society organizations.[32][33]
