Recent studies have advanced the understanding of municipal level party organizational behaviour, highlighting, where present, different levels of institutionalization. These studies, however, only able to show this diversity at a given point in time. This present study aims to describe the process of (i) brazilian municipalities presence by the parties (ii) the organization of this process between 2007 to 2015. At the end of this study, we can see a high variation within these structures on the specified period. Some initial hypotheses can be attributed to these changes. Among them, the profile of the cities influence the political parties in making decisions between making a firm long term commitment to an area or only contesting in local public office elections. Another possibility is that the less organized parties in the municipalities are the very same that are less able to change their state party leadership. These issues are associated with both the organizational capacity a party has with which to pursue its multiple objectives and also the extent to which the internal democratic processes of these institutions allow the base access to the decision making process.
