Dardo Manuel Cabo was an Argentine journalist, activist and militant. Born in the city of Tres Arroyos, he was the son of a notable metalworkers' union leader, Armando Cabo. Dardo Cabo started political activism in the Movimiento Nacionalista Tacuara (MNT), a far-right youth group of the 1960s. Just like several other members of the MNT, he progressively embraced Peronism, and created in 1961 the Movimiento Nueva Argentina, a Peronist right-wing organization.
