Well, she was well on course to become Vice President of Argentina when she died, perhaps she'd end up doing what Juan Perón's third wife Isabel did and become Argentina's first female President.
If she becomes the president, Argentina's economy would have been in toilet by late 60s or early 70s, then she'll take an exile to Spain for the rest of her life together with Juan Peron and Peronism would have been discredited for good. A developed Argentina's economy by today in par with Spain or Italy.
Eva Peron's early death, Juan Peron's ouster during a coup in 1955 and self-exile in Spain for 18 years have had radicalized Peronist supporters all across the political spectrum to destabilize fragile democratic governments of Frondizi and Illia during the 60s which reach to the point where infighting between the Montoneros and the AAA during the 70s became out of the spiral and when Juan Peron died in 1974, it was just a matter of time that the military will have to take over to restore order which happened in 1976, however, the last military junta was more horrible than what the Peronist supports had been doing during the 60s. Because the last military junta was horrible whether economic or political, electorates until now have kept dreaming that the "good days" of first Juan Peron administration will return someday through more government spending beyond the means of the Argentine government.
