postponement of elections. Devoting themselves to damage control, the regime began preparing for the transition by shredding evidence of their murder of 15–30,000 dissidents (most of which were students, academics and labor union personnel uninvolved in the violence Argentina suffered from 1973 to 1976). Hoping to quiet demands that their whereabouts be known, in February 1983 Buenos Aires Police Chief Ramón Camps publicly recognized the crime and asserted that the "disappeared" were, in fact, dead. Provoking popular indignation, Camps' interview forced President Bignone to cease denying the tragedy and, on April 28, declare a blanket amnesty for those involved (including himself). Among the first prominent political figures to condemn the amnesty was the leader of the UCR's progressive wing, Raúl Alfonsín, who easily secured his party's nomination during their convention in July. Alfonsín chose as his running mate Víctor Martínez, a more conservative UCR figure from Córdoba Province. Their traditional opponents, the Justicialist Party, struggled to find candidates for not only the top of the ticket, but for a number of the more important local races, as well. Following conferences that dragged on for two months after the UCR nominated Alfonsín, the Justicialists' left wing (the target of much of the repression before and after the 1976 coup) proved little match for the CGT's influence within the party. They nominated ideological opposites Ítalo Lúder, who had served as acting President during Mrs. Perón's September 1975 sick leave, for President and former Chaco Province Governor Deolindo Bittel as his running mate; whereas Lúder had authorized repression against the left in 1975, Bittel was a populist renowned for his defense of Habeas Corpus during the subsequent dictatorship. Constrained by time, Alfonsín focused his strategy on accusing the Justicialists, who had refused to condemn Bignone's military amnesty, of enjoying the dictator's tacit support. Alfonsín enjoyed the valuable support of a number of Argentine intellectuals and artists, including playwright Carlos Gorostiza, who devised the UCR candidate's slogan, Ahora, Alfonsín ("Now is the Time for Alfonsín"). Lúder, aware of intraparty tensions, limited his campaign ads and rhetoric largely to an evocation of the founder of the Justicialist Party, the late Juan Perón. Polls gave neither man an edge for the contest, which was scheduled for October 30. A few days for the elections (which a record turnout), the Justicialist candidate for Governor of Buenos Aires Province, Herminio Iglesias, threw a (premature) "victory rally" in which
