The Zetas are a large mafia drug organization in Mexico and they have started to give open support to one of the candidates. The pic. says "Take care of your life", and "We the Zetas support our Boss of Bosses - the Candidate's name - to death". The Mexican Army is fighting a civil war against the gangs, and at the same time, for and against its own participation in the trade. In Colombia, the Army won, and probably it will also win in Mexico. The Mexican war has yet to spread north of the border.
