In contrast to most of modern American political history, partisan control of our national elective institutions has been unusually tenuous during the past several decades. This essay series argues that the ideologically sorted parties that contest elections today face strong internal pressures to overreach, by which I mean emphasizing issues and advocating positions strongly supported by the party base but which cause the marginal members of their electoral coalitions to defect. Thus, electoral losses predictably follow electoral victories. Institutional control is fleeting.
The first group of essays describes the contemporary American electorate. Despite myriad claims to the contrary, the data show that the electorate is no more polarized now than it was in the later decades of the twentieth century. What has happened is that the parties have sorted so that each party is more homogeneous than in the twentieth century; liberal Republicans and conservative Democrats have largely passed from the political scene. The muddled middle is as large as ever but has no home in either party. The growth in the proportion of self-identified independents may be a reflection of the limited appeal of today’s sorted parties.
The second group of essays develops the overreach argument, discusses the role of independents as the marginal members of an electoral majority, and explains how party sorting produces less split-ticket voting. Rather than most voters being more set in their partisan allegiances than a generation ago, they may simply have less reason to split their tickets when almost all Democratic candidates are liberals and all Republican candidates are conservatives.
The third group of essays embeds contemporary American politics in two other contexts. First, in a comparative context, developments in the European democracies are the mirror image of those in the United States: the major European parties have depolarized or de-sorted or both, whereas their national electorates show little change. The rise of anti-immigrant parties may have some as yet not well-understood role in these developments. Second, in a historical context, the instability of American majorities today resembles that of the late nineteenth century, when similar significant social and economic changes were occurring.
A final postelection essay will wrap up the series.
