A visit to Rome in 1909 gave the scion of one of Argentina's most powerful families at the time, Roque Sáenz Peña, the opportunity to meet the governing party's nemesis - the exiled leader of the Radical Civic Union (UCR), Hipólito Yrigoyen.

Sáenz Peña, who had been passed over in favor of his aging (and more conservative) father in 1892, was the counterweight President José Figueroa Alcorta needed against the reactionary wing of his party.

[2] Voters in the nation's 14 provinces and Federal District (Buenos Aires) turned out in unprecedented numbers, more than tripling the 199,000 ballots registered in the 1910 elections (the last under the "scripted vote song" scheme that had limited suffrage and produced predictable results since 1862).

[4] What remained of the PAN became the Conservative Party, which retained its dominance in the Senate, albeit a weakened one; but lost its absolute majority in the Lower House, becoming more reliant on the Unión Nacional (whose strength was in western Argentina).

[6] The Buenos Aires race, held on March 30, 1913, resulted in an upset, giving Socialist candidate Enrique del Valle Iberlucea a victory over the UCR's Leopoldo Melo by 42,000 votes to 39,000.
