The three major candidates were populist AndrÃ©s Manuel LÃ³pez Obrador of the Party of the Democratic Revolution (PRD), conservative Felipe CalderÃ³n Hinojosa of the PAN, and Roberto Madrazo of the PRI. Presidential Election Results and Aftermath

After a highly contested election, PAN candidate Felipe CalderÃ³n was named president-elect of Mexico on September 5, 2006, and is due to be sworn into office on December 1, 2006. The Tribunal also found that commercials paid for by business groups at the end of the campaign were illegal but that the impact of the ads was insufficient to warrant the annulment of the presidential election. LÃ³pez Obrador rejected the election tribunal's September 5 ruling and was named the "legitimate president" of Mexico at a democratic convention held on September 16 at the Zocalo, Mexico City's main square. Mexican voters elected a completely new congress on July 2, 2006. Implications for U.S.-Mexico Relations

The United States and Mexico have a multifaceted relationship, with recent emphasis on migration, border security, drug trafficking, trade, and energy policy.
Mexico held national elections for a new president and congress on July 2, 2006. Conservative Felipe CalderÃ³n of the National Action Party (PAN) narrowly defeated AndrÃ©s Manuel LÃ³pez Obrador of the leftist Party of the Democratic Revolution (PRD) in a highly contested election. Final results of the presidential election were only announced after all legal challenges had been settled. On September 5, 2006, the Elections Tribunal found that although business groups illegally interfered in the election, the effect of the interference was insufficient to warrant an annulment of the vote, and the tribunal declared PAN-candidate Felipe CalderÃ³n president-elect. PRD candidate LÃ³pez Obrador, who rejected the Tribunal's decision, was named the "legitimate president" of Mexico by a National Democratic Convention on September 16. The electoral campaign touched on issues of interest to the United States including migration, border security, drug trafficking, energy policy, and the future of Mexican relations with Venezuela and Cuba.
