Eruviel Avila, the Institutional Revolutionary Party's (PRI) gubernatorial candidate in the state of Mexico, shows his ink-stained thumb while holding his identification card after casting his vote in Ecatepec, Mexico, Sunday July 3, 2011. Avila heads into the closely watched race with a 30 percentage point lead. The PRI, which has never lost the governorship in more than 80 years, hopes for a commanding victory to create momentum going into the July 2012 national election, where it wants to regain the presidency it lost in 2000 after 71 years of uninterrupted rule.
