Abstract
The objective of this analysis is to examine political party leadership with reference to the rules and results of its selection process in post-communist Poland. The exploration of these matters is based on qualitative and quantitative data concerning 16 different political parties and 80 selections they conducted in the years 1990-2013. The comprehensive research methods employed for this study ranged from in-depth analysis of particular election results to analysis of constitutional and structural party variations. This extensive investigation enables the reader to draw conclusions about Polish intra-party politics and to understand the vetting processes that Polish politicians must undergo. The findings indicate that political parties tend to address wider selectorates; and that the rules of selection are transparent, democratic, and empirically predictable.
