Argentinians voted Sunday in a presidential runoff, with Buenos Aires Mayor Mauricio Macri the favorite to succeed Cristina Fernandez de Kirchner. Macri, 56, of the centre-right opposition coalition Cambiemos (Let's Change) was up against ruling-party candidate Daniel Scioli, 58, after finishing second to Scioli in the first round of voting on October 25. Macri's supporters started to celebrate immediately after polling stations closed, while media reports announced a Macri win without further details. The election embodies change after 12 years of rule by late president Nestor Kirchner (2003-07) and his wife, Fernandez de Kirchner (2007-15). Argentinian laws ban Fernandez de Kirchner from standing for a third consecutive term, and she backed Scioli, her husband's former vice president. As she cast her ballot in the Patagonian province of Santa Cruz, Fernandez de Kirchner, 62, declined to say whether she would continue to lead her party if Scioli does lose the election to succeed her.
