Democracy in the United States and Europe is said to be at the crossroads. I review five recent books that seek to diagnose and cure this ‘crisis’. Explanations range from institutional dysfunction and elite maleficence to technological change and rising economic inequality. Remedies include everything from institutional engineering to moral persuasion. Collectively, the books raise two important questions: is this really a crisis and if it is, can democratisation theory, the branch of political science dedicated to explaining why regimes rise and fall, tell us why? I conclude that if we are to explain the deconsolidation of well-established democracies in which all of the usual pre-conditions had been met, then we must first question the linear narrative about democracy being a naturally legitimate form of regime.
