MEXICO CITY – Four candidates are in the race to become Mexico's next president in Sunday's election. Here is a look at the aspirants:
ANDRES MANUEL LÓPEZ OBRADOR
In his third attempt as president, López Obrador, a 64-year-old former mayor of Mexico City, is the favorite in most polls.  López Obrador lost the 2006 election by only 0.56 percent to conservative Felipe Calderón, an alleged electoral fraud, and saw his supporters organize a month-long protest camp on one of the busiest avenues in the capital. In 2012, he lost a less controversial race for current president Enrique Peña Nieto.
Born in the southern state of the Gulf coast of Tabasco, López Obrador proclaims himself champion of poor and rural Mexicans. He frequently criticizes the entrenched elite of the country and promises to defeat the "power mafia" that he accuses of rampant corruption.
For years, many members of Mexico's business and political class warned that López Obrador was a populist who would establish the country decades ago, labeling it "a danger to Mexico" and trying to compare it with the late Venezuelan socialist president Hugo Chávez. . But this time, López Obrador has moderated their positions and rhetoric somewhat, and both parties have reached a cautious distension at the end of the campaign even if they are not the best friends.
In addition to addressing corruption, López Obrador has proposed lowering his presidential salary and also grants amnesties to some criminals amid a wave of violence that is the bloodiest seen in at least two decades.
AFFILIATION: National Movement of Regeneration, or Brunette. For many years, López Obrador was a member of the Partido de la Revolución Democrática, or PRD, but in recent years he broke with the group and founded Morena.
NICKNAMES: "AMLO", by its initials; "El Peje", after the pejelagarto fish native to the state of Tabasco; "Andrés Manuelovich", a nickname of López Obrador was joking in response to allegations that his candidacy could have benefited from the Russian meddling.
Anaya, 39, a conservative lawyer with a doctorate in political science, is the youngest candidate to make the presidential election in the modern history of Mexico. His followers see him as a devotee of forward-thinking technology and a shrewd student of politics, while critics call him a calculating and manipulative politician.
Anaya began his political career with only 18 years old, became a legislator in 2012 and later rose to be the speaker of the lower house of the Mexican Congress. He assumed the office of legislator as a result of the rules assigning seats proportionally to the parties, and never won a competitive electoral contest.
Anaya also served as deputy secretary of tourism and became president of his political party, where critics say he used his position to sideline rivals such as former first lady Margarita Zavala.
Born in the State of Mexico, the most populous country in the country, Anaya is the standard bearer of an improbable right-left alliance known as "Adelante para México", which includes her conservative party and two weakened leftist parties.
Some of its main proposals include the creation of a universal basic income, the progressive increase of the minimum wage and the growth of the economy by boosting competition and investment. He accuses Peña Nieto of corruption and says that if he is elected, he will make sure that Peña Nieto "faces justice."
AFFILIATION: National Action Party, or PAN. Lopez Obrador's former party, the PRD, is part of the coalition.
NICKNAMES: "Boy Wonder", for his image of being a young prodigy; López Obrador ridiculed him during a debate like "Ricky Riquin Canallin", which translates roughly as "Richie Rich the scoundrel."
JOSE ANTONIO MEADE
A 49-year-old lawyer with a doctorate in economics from Yale, Meade is a veteran technocrat and a five-time cabinet official who served under two different parties.
Those close to him say that public service is cooked in his DNA, and Meade has served as secretary of energy (2011), treasure (2012), foreign relations (2012), social development (2015) and the treasure again (2016).
Although Meade was not a member of Peña Nieto's ruling party, he was chosen as his candidate in the theory that a stranger would have better luck given the widespread discontent over corruption, increased violence and a slow economy.
But he has struggled to escape the voter's anger with the ruling party, which dominated almost every aspect of Mexican politics. century, and he is is like running third.
Meade's field maintains optimism, announcing internal polls that claim he is in second place and saying he can close the gap with a bunch of voters who are still undecided.
Meade supports a continued military role in fighting powerful drug cartels, would maintain a controversial educational reform and swear to promote schools, hospitals and social programs.
AFFILIATION: Partido Revolucionario Institucional, or PRI.
NICKNAME: "El Mas Chingon", a phrase that translates roughly as "the rudest" and was used by Meade to describe himself after the second presidential debate. A music video cumbia then circulated on social networks using the slogan to promote the candidate.
Rodríguez, 57, is governor of the northern state of Nuevo León and the first person to win a Mexican state office as an independent.
He broke a 30-year alliance with the PRI to make that candidacy for governor in 2015 and was previously mayor of Garcia, near the city of Monterrey, from 2009 to 2012.
Rodriguez has harshly criticized political parties and rejected the government's financing for its presidential campaign. During a debate in April, he suggested cutting the hands of politicians who steal. Asked by the moderator if he meant that literally, he doubled and said he would propose a bill to sanction such punishment.
Polls say he's losing in single digits in a distant room.
NICKNAME: "The Bronco", a nod to both his rider style and his dissolute and quiet person.
