If Peña Nieto wins, he will have to deal with a strong opposition bloc in Congress, and in all likelihood with minority status for the PRI, at least in the lower house. Moreover, more than ten of Mexico’s 32 state governors will belong to the opposition, while the center-left Party of the Democratic Revolution will continue to control the country’s second-most important elected position and budget: the mayor’s office in Mexico City, which the PRD has held since 1997.
