Party switching, or changing one's political party affiliation, is a surprisingly widespread and persistent phenomenon among members of parliament (MPs) in old and new democracies alike. Switching gives voters the impression of a lack of legislator accountability and representation, and may indicate weak parties or government instability. Why do some MPs risk their careers, prestige, and chances of reelection for oftentimes uncertain payoffs? Extant research on party switching frames this behavior as an individual phenomenon, based on rational calculations to further goals of vote, office, or policy-seeking. Yet in the new democracies of Central and Eastern Europe, I find that party switching is largely a group phenomenon, which has heretofore received little attention. Building upon established research on political parties, party systems, and legislator behavior, I develop a theory of group-based defection that addresses this gap in the literature. I argue that MPs pursue political ambition in groups in which they share political goals—the pursuit of collective ambition is thus an alternative means to achieving their objectives. These groups are formed around, or defined by, social identities that are common or shared among individual MPs. By switching political parties as part of a group, individual MPs are able to more effectively pursue their political ambition.
After presenting the theory and hypotheses of group-based party switching as a function of the pursuit of collective political ambition and the importance of shared social identities in Chapter 2, Chapter 3 lays out the dissertation's multi-methodological approach. I present novel biographical and legislative data used to test the theory and hypotheses, discuss the variables used in statistical analyses, and describe the administration of semi-structured interviews. Chapter 4 presents the quantitative analyses of the patterns of group switching in Poland from 1997 to 2011, and the influence of indivi (open full item for complete abstract)
