Electoral Law is the branch of public law intended to study the process of choosing representatives for the occupation of elective offices, including electoral systems and their legislation. The big news of the 2020 municipal elections, the end of party coalitions for the election of councilmen, should require an even more consistent identification of political parties and candidates during the campaign. The pre-campaign gives candidates precisely the time needed for better planning and communication with voters in order to bring great results in community engagement.
