The recent concurrence of violent political rhetoric and violence against political targets in the U.S. and abroad has raised public concern about the effects of language on citizens. Building from theoretical foundations in aggression research, I fielded two nationally representative survey experiments and a third local experiment preceding the 2010 midterm elections to investigate support for violence against political authority. Subjects were randomly assigned to view one of two forms of the same political advertisements. Across all three experiments, mild violent metaphors multiply support for political violence among aggressive citizens, especially among young adults. Aggressive personality traits also predict support for political violence in both national studies. This work identifies dynamic roots of violent political orientations and reveals for the first time surprising interactions between this elite discourse and personality traits in citizens.
