The youth-led Yo Soy 132 movement has urged authorities to overturn the July 1 presidential election. Protesters charge that the vote producing a victory for Institutional Revolutionary Party or Partido Revolucionario Institucional (PRI) candidate Enrique Pena Nieto was marred by fraud and vote-buying.
It is holding a nation-wide march, July 22, 2012, to urge the overturning of the election. This follows a call for the same by the Party of the Democratic Revolution (PRD) candidiate, Andres Manuel Lopez Obrador.
However, Lopez Obrador has ruled out protest camps and blockades.
Thousands of protesters turned out Sunday, but fewer than in past protests against the July 1 election results, according to Huffington Post, this afternoon, "Thousands march in Mexico against election results". Huffington Post ran the following Associated Press report:
Thousands are marching through Mexico City's center and protesting what they call the "imposition" of the candidate of Mexico's old ruling party as the new president.
Marchers are carrying signs and chanting that presumed victor Enrique Pena Nieto won the July 1 election through fraud and vote-buying. He was the candidate of the Institutional Revolutionary Party, or PRI. Rival leftist candidate Andres Manuel Lopez Obrador finished more than six points behind.
The PRI has vehemently denied the charges and on Friday accused Lopez Obrador of trying to "disqualify the entire electoral process with lies."
Authorities did not release an official crowd estimate, but the march appeared to draw fewer people than similar protests with as many as 90,000 participants. The events have attracted people from a new student movement and leftist groups supporting Lopez Obrador.
