Andres Manuel Lopez Obrador called on a huge crowd of supporters to keep protesting while he pursues a legal challenge of Mexico's disputed presidential vote count, and to help him prevent "a backward step for democracy." The fiery, silver-haired leftist said he would begin presenting his allegations to the nation's electoral court on Sunday, requesting that all 41 million votes cast be recounted to expose fraud he believes cost him the election. "We are going to ask that they clean up the elections. We are going to ask that they count all the votes, vote-by-vote, poll-by-poll," Lopez Obrador said, calling on the army to protect the integrity of every ballot box. He also called for marches nationwide, beginning Wednesday and converging on Mexico City for another rally on Sunday July 16, according to a report of the Associated Press.
