In this comparative case-study, elements of diffusion theory are used to examine local conditions conducive to political organization in terms of independent local lists (ILLs). Empirical evidence supports the formulation of three hypotheses for future and more systematic research into the problem: a hypothesis of size, an elite-hypothesis and a mobilization-hypothesis. Although several factors are likely to play a role, the results suggest particularly that ILLs are less likely to occur in localities lacking historical legacies in terms of popular mobilization.
