Mexico's presidential candidates are making a big push in the last weekend of campaigning ahead of the July 1 vote to win over undecided voters.

Josefina Vazquez Mota, of the governing National Action Party, or PAN, staged a rally attended by nearly 10,000 supporters Saturday at Mexico City's Monumental bullring, telling the crowd she planned to "cut the two ears and the tail" in the election.

Vazquez Mota said she planned to prove the polls wrong by winning the election with the backing of Mexico's "silent majority."

"The polls showed them down, but we won because there is a silent majority that is going to come out at the ballot box," Vazquez Mota said, referring to gubernatorial elections in which the public opinion surveys proved to be wrong.

The PAN candidate is currently running second in the polls for next Sunday's election.

Vazquez Mota is trailing frontrunner Enrique Peña Nieto, of the Institutional Revolutionary Party, or PRI, by six points and is ahead of leftist candidate Andres Manuel Lopez Obrador.

Peña Nieto met on Saturday morning with the National Political Action Committee of the SNTE teachers union, calling for its support to improve the educational system.

The PRI candidate vowed to improve teachers' training, expand and renovate educational infrastructure, and ensure that students in the upper grades have access to computers.

The presidential frontrunner said he was the only candidate who could change the perception abroad of Mexico as an unsafe country, not via diplomatic negotiations or international agreements, but "through what we achieve domestically."

"When we manage to once again put Mexico on the path to peace, security and economic growth, the eyes of the world will once again turn to Mexico," Peña Nieto said.

Peña Nieto traveled later in the day to Guanajuato state, where he took part in a rally in the city of Irapuato with Juan Ignacio Torres, who was wrapping up his gubernatorial campaign.

Lopez Obrador, the candidate of a leftist coalition led by the Party of the Democratic Revolution, or PRD, participated in a rally in the southern state of Chiapas, calling on young people to play a role in the political life of the country.

The youth vote has moved toward Lopez Obrador in recent weeks, with users of social-networking sites helping promote his candidacy.

"I want to issue an invitation to all the users of social networks to contribute actively to bringing about democratic change beyond the Internet," the former Mexico City mayor said.

Lopez Obrador asked social-network users to help turn out supporters for a massive march on Wednesday to close the campaign and urged them to keep an eye on polling places on election day to prevent fraud.

The leftist politician has blamed his narrow defeat at the hands of the PAN's Felipe Calderon in the 2006 presidential election on fraud.

"The young people in the social networks and in the streets have awakened the consciences of millions of citizens with their rebelliousness, imagination and joy," Lopez Obrador said during the rally in Tuxtla Gutierrez, the capital of Chiapas.

The leftist candidate vowed that if he was elected president, no one in his family would get a government post.

New Alliance Party, or PANAL, candidate Gabriel Quadri, who is a long shot to win, called on supporters in Tlalnepantla, a city in Mexico state, to make their votes count so that "we do not once again reward the politicians who always trick us."

Nearly 80 million Mexicans will be eligible to vote for a new president, 628 legislators and thousands of other officials in the general elections. EFE
