Wearng a Guy Fawkes mask, a protester holds a banner that reads in Spanish, "No to another fraud," during a march in Mexico City on Saturday.
The demonstrators, including students, leftists, anarchists and union members, shouted slogans criticizing Pena Nieto's Institutional Revolutionary Party, or PRI, and the electoral authority.
Pena Nieto won Sunday's election by almost 7 percentage points, according to the official count, returning the PRI to presidential power after 12 years in the wilderness.
The PRI previously ruled Mexico for seven decades, during which time it was accused of rigging elections and repressing protesters.
"The PRI threatens many people and buys others with a couple of tacos," said Manuel Ocegueda, a 43-year-old shop worker participating in the march.
Pena Nieto is due to take power in December, replacing Felipe Calderon of the conservative National Action Party, or PAN.
The constitution barred Calderon from running for a second term. The PAN candidate, Josefina Vazquez Mota, finished third, with many voters dissatisfied over relentless drug violence and sluggish growth.













Comment: This situation would not be possible without the complicity of New York City government. There is apparently plenty of money to clean up and maintain the tourist areas, but none to devote to keeping the city livable for the residents.
