I examine how the chief executives political party affects domestic terrorism within democracies. In particular, I contribute to the literature on terrorism within democracies by arguing that domestic terrorist groups prefer attacking when right-wing parties hold office. I find evidence for this claim as well as results indicating that left-wing executives are more likely to cut deals with domestic terrorist groups. These trends suggest that domestic terrorist groups attack during right-wing governance to build their reputation and reduce violence during left-wing governance to appear moderate and get a deal. These results contribute to literatures on differences between left and right parties, how political institutions affect terrorism, and differences between domestic and transnational terrorism.
