This does not bode well:
Riot police suppress protests calling for new elections in Tucumán

Allegations of electoral fraud bring demonstrators out on the street in Argentinean province

At stake was the governorship of Tucumán, where Alperovich and his associates from President Cristina Fernández de Kirchner’s Front for Victory (FPV) coalition manage a $3 billion dollar budget as they please. If no new elections are held, his vice-governor, Juan Manzur, will soon take over.
. . .
Though the province is the nation’s smallest, it has the fifth largest population and has now become the site of a landmark moment in this election season. According to preliminary results, presidential election favorite Daniel Scioli’s center-left FPV coalition won Tucumán by 14 points but this victory may cost him, with images of irregularities on the day of voting and other fraudulent maneuvers threatening to damage his standing.

The sign reads, “I don’t fear the state’s repression.
I fear the people’s silence.”
