Municipio X

The president of the municipio is directly elected by citizens. The Council of the municipio is elected every five years, with a system under which voters express a direct choice for the President or an indirect choice voting for the party of the candidate's coalition. If no candidate receives at least 50% of votes, the top two candidates go to a second round after two weeks. This gives a result whereby the winning candidate may be able to claim majority support.

Last election occurred on 3 and 17 October 2021:
