Here's how a New York Times journalist portrays the presidential candidates... For the entire three page article, see the link below the quote.
"Enrique Peña Nieto, the telegenic front-runner sometimes called the Pretty Boy (or Gel Boy because of his styled hair), needs to persuade voters that he represents a new, corruption-free Institutional Revolutionary Party, or P.R.I., the party that ruled Mexico from 1929 to 2000. But can he prove he is not just a handsome meringue atop an old authoritarian party?
Josefina Vázquez Mota, a former education secretary under the current president, has perhaps a greater challenge. She has been called the Quinceañera Doll because she is always smiling, but her party — the P.A.N., orNational Action Party — has been in charge for 12 years, a time of rising violence and continued corruption. Can she convince Mexicans that she represents a break from her party and become the country’s first female president?
And even for Andrés Manuel López Obrador, a liberal former mayor of Mexico City who lost the last election in 2006 by 0.6 percentage points, the past and future compete. The oldest of the candidates, sometimes called the Tired Has-Been, he must answer the question of whether he has put aside the radical populism of his last campaign to govern as a moderate."
