Welcome! I’m Mike, a postdoctoral researcher at the European University Viadrina. I work at the European New School of Digital Studies in the Chair of Digital Democracy.

My research interests include intra-party factions, candidate selection, and political communication. My forthcoming book examines U.S. intra-party factions in congressional primary elections in the twenty-first century and considers their contribution to trends of partisan polarization in Congress.

I also serve as the co-PI of the Digital Campaigns & Elections (DiCE) Lab: www.dicelab.eu

Party Transformation in Congressional Primaries

Forthcoming. Cambridge University Press.

Party Transformation in Congressional Primaries explains how the process through which candidates run for Congress fundamentally changed during the twenty-first century. These changes then reverberated in polarizing the parties in Congress. Primaries are commonly said to drive polarization because of the people who vote in them, but I show instead that the nomination process exacerbates polarization through the influence of elite party actors causing candidates to adopt more ideological behavior.
