The Mexican Democratic Party (PDM) traces its origins to the Manuel Torres Bueno faction of the National Synarchist Union (UNS), a right-wing Catholic and clerical fascist organization.

By the 1970s, the UNS experienced a revival due to electoral reforms introducing proportional representation, which allowed smaller political groups to participate in elections.

The PDM sought to formally engage in electoral politics to challenge the dominance of the Institutional Revolutionary Party (PRI) and provide a platform for Catholic conservatives, particularly in rural communities.

[7] It was in the old UNS heartlands that the PDM obtained its greatest electoral presence, prevailing in several important municipalities like Lagos de Moreno in Jalisco or the city of Guanajuato.

The party’s failure to adapt to the changing dynamics of Mexico’s political system and its inability to attract new sectors of the population also contributed to its decline.

[13] Unlike the more moderate National Action Party (PAN), which appealed to urban middle-class voters, the PDM primarily drew support from rural lower-class communities, including farmers and landowners.

[14] The party also sought to address the interests of the “petty-bourgeois” rural population by advocating for reforms aimed at correcting perceived injustices in Mexican capitalism.
