The president left on foot with his wife from the National Palace where they live in an interior apartment, and arrived amidst applause from occasional witnesses who also lined up to cast their ballots.
Once there, the presidency couple followed the established sanitary protocols, took their temperature and placed their hands so that the person in charge of that task could put gel on their hands and another one could give them the respective credentials.
After the procedure was completed, they entered the precinct and lined up like any other ordinary citizen until it was their turn to go to the ballot boxes, where they deposited their ballot papers, once they had filled them out according to the established personal reservations.
They immediately went to the table where one of their fingers was dyed with indelible ink as a sign that they had voted and as a guarantee that they would not be able to cheat by voting two or more times since the finger would remain dark for several hours.
The married returned to the outside of the old archbishopric and before receiving sanitary gel again, they exhibited their stained thumbs so that photographers and cameramen could testify that they exercised their rights in those crucial elections.
The whole ceremony lasted exactly seven minutes and without uttering words or sending messages to the nation as almost all the head of States worldwide usually do in these occasions, they set off on foot as they arrived at the National Palace in Zocalo downtown.
The elections have begun calmly and are expected to remain so throughout the day.
Authorities are expected to report preliminary results after 8:00 p.m. local time.
