Mexico holds its presidential election on Sunday, and with almost 80 million Mexicans eligible to vote at more than 141,000 polling locations, the country is hoping for a positive change.

Voters will also be selecting Mexico City’s mayor and governors for the states of Yucatan, Tabasco, Morelos, Jalisco, Guanajuato and Chiapas.

The candidates for this presidential election are 45-year-old Enrique Pena Nieto, 58-year-old Andres Manuel Lopez Obrador, 57-year-old Gabriel Quadri de la Torre and 51-year-old Josefina Vazquez Mota.

Nieto is a member of the Institutional Revolutionary Party and a former governor. He is also married to a soap-opera star.

Obrador is a candidate of the Democratic Revolution Party and a former Mexico City mayor.

De la Torre is a candidate of the New Alliance Party.

Mota is a member of the National Action Party and is the first female candidate representing the party. She is also the first female to run for president from a major political party.

Polling stations open at 8 a.m. CT and close at 6 p.m. CT. The first exit polls are expected by 8 p.m. CT, and the country will release the results of the quick count of select polling places at 11:45 p.m. CT.

The current president cannot stand for re-election after serving a six-year term.

Soliders are stepping up security along border cities and it is not clear how the drug cartel violence will impact voter turnout at the polls.
