Leftist presidential candidate Andres Manuel Lopez Obrador has gained 7 more percentage points in a poll released Thursday and is closing in on frontrunner Enrique Peña Nieto, the Mexico City daily Reforma said.

Lopez Obrador, standard-bearer of the Party of the Democratic Revolution, or PRD, the Workers Party, or PT, and the Citizens Movement, is drawing the support of 34 percent of likely voters, just 4 points behind Peña Nieto, of the Institutional Revolutionary Party, or PRI, which governed Mexico from 1929 to 2000.

Conservative Josefina Vazquez Mota, of the governing National Action Party, or PAN, is getting the backing of 23 percent of likely voters, while Gabriel Quadri, of the New Alliance Party, or PANAL, drew just 5 percent support.

"I am very happy" about the poll numbers, Lopez Obrador said in a press conference in the capital.

The former Mexico City mayor said Peña Nieto, whom he referred to as "the candidate of television," was "deflating."

Lopez Obrador narrowly lost the 2006 presidential election to the PAN's Felipe Calderon.

An April 25 poll published by the same newspaper showed Peña Nieto with 42 percent support and Lopez Obrador drawing only 27 percent support, while Vazquez Mota was getting 29 percent support.

The poll of 1,515 registered voters, which was conducted May 24-27, has a margin of error of 2.9 percentage points and excludes undecided voters, Reforma 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
