How Cycles of Polarization and Depolarization Shape the Exercise of Judicial Review

The cycle of polarization and depolarization affects the political supports for judicial review. When politics is depolarized, politicians tend to let judges handle basic constitutional questions so that politicians can fight over the spoils of everyday politics. Judicial review tends to enforce the values of national political elites, especially against state and local governments. When the country is polarized, however, elite consensus evaporates. Political elites disagree about everything, so judicial review cannot do the same work. Instead, judicial review allows polarized political elites to win victories they can no longer win in the political process. As legislative politics becomes mired in polarization, the judiciary becomes an ever more important venue for achieving policy victories. This increases the urgency and bitterness of partisan fights over judicial appointments. Strong polarization encourages the parties to engage in constitutional hardball to secure ideologically aligned judges and prevent the other party from appointing judges.
