2012 Mexican general election in the context of Senate of the Republic (Mexico)

Enrique Peña Nieto OMRI CYC GCB (Spanish pronunciation: [enˈrike ˈpeɲa ˈnjeto] ; born 20 July 1966), commonly referred to by his initials EPN, is a Mexican former politician and lawyer who served as the 64th president of Mexico from 2012 to 2018. A member of the Institutional Revolutionary Party (PRI), he previously was Governor of the State of Mexico from 2005 to 2011, local deputy from 2003 to 2004, and Secretary of Administration from 2000 to 2002.

Born in Atlacomulco and raised in Toluca, Peña Nieto attended Panamerican University, graduating with a B.A. in legal studies. After attaining an MBA from ITESM, he began his political career by joining the Institutional Revolutionary Party (PRI) in 1984. After serving as a public notary in Mexico City, he began an ascent through local political ranks in the late 1990s, culminating in his 2005 campaign for Governor of the State of Mexico. As governor, he pledged to deliver 608 compromisos (commitments) to his constituency to varying levels of success. His tenure was marked by low-to-moderate approval of his handling of a rising murder rate, the San Salvador Atenco civil unrest, and various public health issues. He launched his 2012 presidential campaign on a platform of economic competitiveness and open government. After performing well in polls and a series of high-profile candidate withdrawals, Peña Nieto was elected president with 38.14% of the vote.

The National Action Party (Spanish: Partido Acción Nacional, PAN) is a conservative political party in Mexico founded in 1939. It is one of the main political parties in the country, and, since the 1980s, has had success winning local, state, and national elections.

In the historic 2000 Mexican general election, PAN candidate Vicente Fox was elected president, the first time in 71 years that the Mexican presidency was not held by the traditional ruling party, the PRI. Six years later, PAN candidate Felipe Calderón succeeded Fox after winning the 2006 presidential election. In the 2006 legislative elections, the party won 207 out of 500 seats in the Chamber of Deputies and 52 out of 128 senators. In the 2012 legislative elections, the PAN won 38 seats in the Senate and 114 seats in the Chamber of Deputies, but the party did not win the presidential election in 2012, 2018, or 2024. The members of this party are colloquially called panistas.
