 Apart from Bartolomé Mitre, politicians associated with the National Civic Union included Guillermo Udaondo and Honorio Pueyrredón.The Civics and the Radicals proved to be close on most issues, and tended to collaborate.In 1896 the personal link between Mitre and Radical Bernardo de Irigoyen gave rise to the so-called "política de las paralelas", whereby the two parties appointed candidates to a common electoral list.
