In her memoir published this year, “Sinceramente” (“Sincerely”), Mrs. Kirchner suggested that President Mauricio Macri and his wife (both of whom have been divorced and remarried) do not fit the image of the perfect family they are made out to be. She made comparisons to her own union with Mr. Kirchner, which was the only marriage for both and lasted 35 years, until his death in 2010.

Recently, Mrs. Kirchner has expanded her views on issues related to feminism. During her nearly decade-long tenure as president she opposed the legalization of abortion. When the press asked her how she felt about so-called women’s issues, she famously declared that she is “a Peronist, not a feminist.”

When the grass-roots women’s rights movement Ni Una Menos (Not One Less) started out in 2015 with a huge street protest against the rise in gender-related killings of women, Mrs. Kirchner was the sitting president. She later wrote that she had seen Ni Una Menos as an opposition force. Then, in 2018, apparently moved by the global hue and cry of both Ni Una Menos and the #MeToo movement, Mr. Macri opened up a national debate over a bill that would have allowed abortion. This time, seemingly enthused by her role in the opposition, Mrs. Kirchner voted in favor of legalization.

The former president understands the dynamics of power like no one else in Argentina. If Evita — whose untimely death from cancer added to her myth — was revered as a supporter of the downtrodden, Mrs. Kirchner crafts her allure as the resilient widow who survives it all: the death of Mr. Kirchner, the corruption charges, the growing list of traitors. In fact, Mr. Fernández, the president-elect, had become a foe when he left his post as Mrs. Kirchner’s cabinet chief in 2008 to organize a new Peronism without her.
