Ideology and Spatial Voting in American Elections addresses two core issues related to the foundations of democratic governance: how the political views of Americans are structured and how citizens' voting decisions relate to their ideological proximity to the candidates. Focusing on testing the assumptions and implications of spatial voting, this book connects the theory with empirical analysis of voter preferences and behavior, showing Americans cast their ballots largely in accordance with spatial voting theory. Stephen A. Jessee's research shows voters possess meaningful ideologies that structure their policy beliefs, moderated by partisanship and differing levels of political information. Jessee finds that while voters with lower levels of political information are more influenced by partisanship, independents and better informed partisans are able to form reasonably accurate perceptions of candidates' ideologies. His findings should reaffirm citizens' faith in the broad functioning of democratic elections.

Political Ideologies and Political Parties in America puts ideology front and center in the discussion of party coalition change. Treating ideology as neither a nuisance nor a given, the analysis describes the development of the modern liberal and conservative ideologies that form the basis of our modern political parties. Hans Noel shows that liberalism and conservatism emerged as important forces independent of existing political parties. These ideologies then reshaped parties in their own image. Modern polarization can thus be explained as the natural outcome of living in a period, perhaps the first in our history, in which two dominant ideologies have captured the two dominant political parties.

A pioneering effort to integrate ideology with formal political theory

Formal Theories of Politics demonstrates the role of formal mathematical models in political science, and aims to convey a sense of the questions and methods which govern the political science research agenda. While there is still much interest in empirical patterns of voting behaviour and public opinion data, there has been substantial growth in emphasis on mathematical theory as a technique for the derivation of testable hypotheses. Topics discussed include: optimal candidate strategies and equilibria in competitive elections; voting agendas and parliamentary procedure in the multidimensional events; revolution, repression and inequality as outputs of dynamics systems. The mathematical techniques are widely varied, including game theory, functional analysis, differential equations, expert systems, stochastic processes and statistical models.
