Elections in Mexico determine who, on the national level, takes the position of the head of state – the president – as well as the legislature.

The President of Mexico is elected for a six-year term by the people. The candidate who wins the most votes is elected president even if he or she does not have an absolute majority.

In Mexico, every presidential election will always be a non-incumbent election.

The Congress of the Union (Congreso de la Unión) has two chambers. The Chamber of Deputies (Cámara de Diputados) has 500 members, elected for a three year term, 300 of whom are elected in single-seat constituencies by plurality, with the remaining 200 members elected by proportional representation in 5 multi-state, 40-seat constituencies. The 200 PR-seats are distributed generally without taking account the 300 plurality-seats (Parallel voting), but since 1996 a party cannot get more seats overall than 8 % above its result for the PR-seats (a party must win 42% of the votes for the PR-seats to achieve an overall majority). There are two exceptions on this rule: first, a party can only lose PR-seats due to this rule (and no plurality-seats); second, a party can never get more than 300 seats overall (even if it has more than 52% of the votes for the PR-seats).

Mexico (ⁱ/ˈmɛksɨkoʊ/; Spanish: México, IPA: [ˈmexiko] ( listen)), officially the United Mexican States (Spanish:  Estados Unidos Mexicanos (help·info)), is a federal constitutional republic in North America. It is bordered on the north by the United States of America; on the south and west by the Pacific Ocean; on the southeast by Guatemala, Belize, and the Caribbean Sea; and on the east by the Gulf of Mexico. Covering almost two million square kilometres (over 760,000 sq mi), Mexico is the fifth largest country in the Americas by total area and the thirteenth largest independent nation in the world. With an estimated population of over 113 million, it is the eleventh most populous country and the most populous Spanish-speaking country. Mexico is a federation comprising thirty-one states and a Federal District, the capital city.

In Pre-Columbian Mexico many cultures matured into advanced civilizations such as the Olmec, the Toltec, the Teotihuacan, the Zapotec, the Maya and the Aztec before the first contact with Europeans. In 1521, Spain conquered and colonized the territory from its base in México-Tenochtitlan, which was administered as the Viceroyalty of New Spain. This territory would eventually become Mexico as the colony's independence was recognized in 1821. The post-independence period was characterized by economic instability, the Mexican-American War and territorial cession to the United States, a civil war, two empires and a domestic dictatorship. The latter led to the Mexican Revolution in 1910, which culminated with the promulgation of the 1917 Constitution and the emergence of the country's current political system. Elections held in July 2000 marked the first time that an opposition party won the presidency from the Institutional Revolutionary Party.

Gregory Allyn Palast (born June 26, 1952) is a New York Times-bestselling author and a freelance journalist for the British Broadcasting Corporation as well as the British newspaper The Observer. His work frequently focuses on corporate malfeasance but has also been known to work with labor unions and consumer advocacy groups. Notably, he has claimed to have uncovered evidence that Florida Governor Jeb Bush, Florida Secretary of State Katherine Harris, and Florida Elections Unit Chief Clay Roberts, along with the ChoicePoint corporation, rigged the ballots during the US Presidential Election of 2000 and again in 2004 when, he argued, the problems and machinations from 2000 continued, and that challenger John Kerry actually would have won if not for disproportional "spoilage" of Democratic votes.

Palast spoke at a Think Twice conference held at Cambridge University and lectured at the University of São Paulo. He lives in New York City. Palast is originally from Los Angeles, and was educated at the University of Chicago, and eventually earned an MBA.

John Bevier Ackerman (April 29, 1909 – June 13, 1981) was the second Vice Director of the National Security Agency of the United States and a Major General of the United States Air Force.

Lucia Newman (born February 18, 1952 in London) is a reporter for Al Jazeera English and former reporter for CNN. In 1991, she received the Maria Moors Cabot prize from Columbia University for contributing to "the advancement of press freedom and inter-American understanding".

In March 1997, Newman became the first United States journalist (although she is actually British) in twenty-seven years to have permanent residence in Cuba.The North-South Institute praised her reporting and wrote that because she knows several languages, "she can find out things others cannot". Newman is fluent in English, Spanish, French, and Portuguese. However, after Newman's first news broadcast, Ninoska Pérez Castellón criticized her for not interviewing people who were against the Cuban government. Pérez wanted Newman to show Cuba as a "normal place", not a "rogue nation".

Newman has reported for CNN in a number of Latin American countries. She reported in Panama. On September 16, 1987, the Panama government expelled Newman from the country after a mob saw her grinning during an interview with Manuel Noriega. Oriega called her a "disinformer". She was a correspondent in Nicaragua during 1985 to 1989 and in Chile from 1989 to 1993. From 1993 to 1997, Newman was head of CNN's bureau in Mexico. In 2006, she departed from CNN and became a reporter for Al Jazeera English.
