La candidata ecologista Marina Silva rimane la favorita alle elezioni presidenziali brasiliane che si terranno il prossimo 5 ottobre, ma la presidentessa uscente, Dilma Rousseff, sta riguadagnando terreno. È quanto emerge da un sondaggio pubblicato mercoledì.
Secondo quanto stimato dall’istituto Datafolha, al primo turno le due donne sarebbero tecnicamente in parità, con la Rousseff che otterebbe il 34% delle preferenze, un solo punto percentuale in meno della Silva.
Le previsioni danno comunque quest’ultima vincente al secondo turno anche se con un margine meno netto di quanto stimato in precedenza. L’accorciarsi delle distanze coincide con un rafforzamento della campagna della Rousseff, che critica le “incoerenze” del programma dell’avversaria che aveva rimpiazzato l’alleato del partito socialista Eduardo Campos, deceduto il 13 agosto in un incidente aereo. In particolare sono messe in dubbio le capacità della Silva di formare una maggioranza parlamentare stabile.
