A state governor said Mexico is ready to have a female president and did not rule out the possibility that her Institutional Revolutionary Party, or PRI, will one day nominate a woman for the top spot.

"Mexicans have evolved and they now put greater value on ability than gender," Yucatan state Gov. Ivonne Ortega, currently the only woman among Mexico's 32 governors, told Efe in an interview.

She said the PRI, whose 71-year grip on power ended when the conservative National Action Party, or PAN, won the 2000 election, could opt for a female standard-bearer in future presidential contests.

A total of four women have run for Mexico's highest office - Rosario Ibarra, Marcela Lombardo, Cecilia Soto and Patricia Mercado.

No female candidate has yet thrown her hat in the ring in the 2012 presidential race, although former Cabinet member Josefina Vazquez Mota has expressed interest in seeking the PAN nomination.

In the case of the PRI, erstwhile party chair Beatriz Paredes could add her name to the list although she has said previously that the presidency is not her main objective.
