TWO of Latin America’s three biggest economies, Brazil and Argentina, are headed by women (see article and article). Might Mexico make it a clean feminist sweep next year? The ruling National Action Party (PAN) has been struggling to find a popular candidate for the presidential election in 2012 (the constitution bars the president, Felipe Calderón, from seeking a second term). The opposition has mocked the PAN’s hopefuls as the “seven dwarves”. The American ambassador privately described them as “grey”. (He was withdrawn soon after the offending cable was leaked.) But polls suggest that Josefina Vázquez Mota, the PAN’s leader in the Chamber of Deputies, is emerging as a possible technicolour candidate.
