Presidential candidate Andres Manuel Lopez Obrador said during an appearance on a national television show that if elected, he would form a national reconciliation government that would seal agreements with all sectors of Mexican society.

Lopez Obrador appeared on Televisa's "Tercer Grado" show on Wednesday with some of the network's top news hosts and pundits from Grupo Milenio.

The leftist candidate accused the news personalities of being "sympathizers" of Institutional Revolutionary Party, or PRI, candidate Enrique Peña Nieto, who is the frontrunner in the presidential race.

Lopez Obrador said the only impartial member of the panel was Victor Trujillo, who is better known as the mocking, cutting and critical "Brozo" the clown.

The former Mexico City mayor's appearance was marked by sharp differences and exchanges of recriminations with the pundits, with many questions left unanswered.

Lopez Obrador stuck to his stump speech, saying that he is the only candidate able to solve Mexico's problems because he is honest, cannot be bought and has a desire to serve the people.

The leftist candidate, standard-bearer of the Party of the Democratic Revolution, or PRD, Workers Party, or PT, and Citizens Movement coalition, downplayed the fact that he is trailing Peña Nieto by 12 points in the polls.

The majority of polling firms "come to an agreement in general" to support their candidate since they have commitments to keep and are well paid, as was seen in some cases in the 2006 elections, Lopez Obrador said.

"The polls are all part of political propaganda," Lopez Obrador said.

The former Mexico City mayor narrowly lost the 2006 presidential election to Felipe Calderon, of the National Action Party, or PAN.

Lopez Obrador said polls conducted by his campaign show that he has the support of 28 percent of likely voters to Peña Nieto's 26 percent, while the PAN's Josefina Vazquez Mota has the backing of 19 percent of likely voters.

The latest Consulta Mitofsky poll showed Lopez Obrador gaining ground for the fourth week in a row, with his support among likely voters rising from 27.4 percent to 29.2 percent, but he is still trailing Peña Nieto by 14.4 points.

Peña Nieto's poll numbers have dropped in the wake of the emergence and rapid growth of the Yo soy 132 movement, which is made up of university students unhappy with Mexico's political system.

The movement is non-partisan, but it has expressed opposition to Peña Nieto's candidacy and the power wielded by Mexico's large television networks.

"I am the leader of a movement, but the citizens are the engine of change. There is an organization. I am sure we are going to win," Lopez Obrador said.

Millions of people will turn out on election day to monitor polling places and prevent fraud, Lopez Obrador said.

The leftist politician rejected allegations of corruption by associates during his 2000-2005 term as head of the Federal District's government and in his two presidential campaigns as "unfounded" or "manipulation."

Lopez Obrador said he played no role in a recent meeting at which supporters asked for help in raising $6 million for the campaign.

A Lopez Obrador administration would be characterized by honesty and tolerance, with all sectors of society playing a role, the presidential candidate said.

Mexico will hold its presidential election on July 1, selecting a successor to President Calderon.

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
