At this rate, this will be remembered as the Bad Book Criticism election, which does not speak well of the contest nor its participants. This mistake is from Josefina Vázquez Mota, though it is significantly less embarrassing than either Fox's on Twitter or Peña Nieto's at the FIL in Guadalajara. (She mixed up the authors of one wonky book on Mexico's future--Jorge Castañeda and Héctor Aguilar-- with the authors of another wonky book on Mexico's future.) Nonetheless, it is another misstep from a campaign that seems incapable of actually stepping straight forward.
It also strikes me as ironic that the article linked above misspells Castañeda's last name, calling him "Catañeda". Fox's foreign minister just can't win today.
