Carlos Lencinas enrolled at the National University of Córdoba, and upon earning a Law Degree, returned to Mendoza and joined his father as a local leader of the Radical Civic Union (UCR).

[1] His father's progressive social and economic policies endeared him to the then-agrarian province's sizable population of tenant farmers and peons, many of which were victims of debt bondage.

They also made enemies of the province's landowning elite, however, as well as of the reformist President Hipólito Yrigoyen, who sought the latter group's support, and had Lencinas removed as governor in late 1919.
