FILE - In this Aug. 20, 2010 file photo, Mexico City's Attorney General Miguel Angel Mancera, center, looks on during the presentation of a new elite police group in Mexico City. Mancera, who is running for mayor of Mexico City, holds an astonishing lead of about 50 points in polls going into the July 1 vote, which coincides with the 2012 presidential election. Mancera is campaigning on his reputation as the city's attorney general and a 12 percent drop in crime from 2010 to 2011. (AP Photo/Alexandre Meneghini, File) less
