Rodríguez Larreta: "We need a real Minister of Economy, who has all the buttons that make the economy work" "There has to be a healthy combination of people with experience, plenipotentiary, like Massa, Lavagna or Cavallo," he says. "I am going to be the first president of Argentina as an economy minister," says the former mayor of Buenos Aires, who is running for re-election in the Buenos Aires governorship.
