General elections were held in Mexico on Sunday, 2 July 2006. Voters went to the polls to elect a new President of the Republic to serve a six-year term, replacing then President Vicente Fox (ineligible for re-election under the 1917 Constitution); 500 members of the Chamber of Deputies (300 by the first-past-the-post system and 200 by proportional representation) to serve for three-year terms; and 128 members of the Senate (three per state by limited voting and 32 by proportional representation from national party lists) to serve for six-year terms.
Several local ballots were also held on the same day, including the head and legislature of the federal district, governors of Guanajuato, Jalisco and Morelos and local councillors in several states.
