The survey was based on a survey of 600 to 698 cases. It was done by CB Consultora Opinión Pblica.

In Greater Buenos Aires, 20 of the 24 communal leaders are from the PJ. The one who broke JxC's streak was Leonardo Nardini, mayor of Malvinas Argentinas. He refers to the old guard "Peronist of Peron" and is a cogenerational member of La Cámpora. He was also mayor of Hurlingham, La Matanza, San Martn, and Julián Alvarez. The six worst mayors of the Buenos Aires suburbs belong to the PJ, the survey found. The only party in which he retains more support than rejection is San Isidro. It raised a strong alert for President Javier Milei, who was re-elected last month.
