Oops, I spoke too soon. It looks like Eduardo Enrique "Wado" de Pedro is the chosen one and if you haven't heard of him, I don't blame you.
(During the last dictatorship, Wado de Pedro was kidnapped as a baby by military forces in an operation in which his mother was murdered. Three months after his abduction, the military returned him to his family.)
He's the interior minister and as grey as they come. A perfect patsy.
Correction: it's La Campora that's pushing him as the candidate.
