The tenuous organisational structure of the Venezuelan neighbourhood movement explains its failure to live up to the lofty expectations which social movements created in Latin America in the 1980s. To understand why structural looseness prevails, it is necessary to examine social cleavages as well as the disparity between the theoretical model which underpins much discourse and legislation, on the one hand, and the daily practice of neighbourhood associations, on the other. An additional area of enquiry is the division in the national leadership between an apolitical current and one that views electoral politics as a natural avenue for the movement to pursue. Scholars, even those who have recently emphasized the importance of links between social movements and political structures, overlook the importance of organisational unity at the national level.
