As much for the political parties as for the candidates, the electoral period is key. It is when they are most active, they are more visible in the media and seek closer contact with the voters and their supporters. It seems that some political parties exist mostly as campaign machines, because they are almost invisible in the periods between elections.
During the electoral campaign, the propaganda apparatus, speeches and visits to different places are fundamental.
In the electoral process, the most important role played by political parties is the control of the process. The parties aim to ensure the guarantees and compliance with current legislation in this regard.
