In the wake of the tumultuous Kavanaugh hearings marked by wrenching accusations of sexual assault and extreme examples of political bullying, in Part Three I focus on the two major political parties to explore why over the years Republicans and their right-wing supporters have freely resorted to extremely aggressive political tactics and — just as important — why Democratic Party leaders and their liberal allies have often failed to take seriously such acts of political violence and skullduggery by their opponents and respond accordingly. Part of the answer, I argue, lies in their respective practices of loyalty and identity, social composition, and conceptions of governing.
