Obrador holds commanding lead ahead of Mexico elections Sunday

June 29 (UPI) -- Elections this weekend are expected to shake up the Mexican government, as poll numbers project major wins for presidential candidate Andres Manuel Lopez Obrador and his leftist party.

The Movimiento Regeneracion Nacional, or Morena, Party is led by Obrador, known by his initials AMLO, who holds a notable lead of more than 20 points over conservative candidate Ricardo Anaya in the presidential race -- with two days remaining.

"If AMLO wins by a significant threshold and gets a majority in congress, that will signal a very significant shift in Mexican politics on a very fundamental level," said Latin America analyst Reggie Thompson. "If he doesn't get a majority, ... he'll be far less powerful."

Obrador's platform includes free access to telecommunications services like the Internet and pension increases for the elderly. He also wants to reverse key reforms made by President Enrique Pena Nieto's administration that opened the country's energy industry to foreign companies. He's also pledged to fight widespread corruption, something that added momentum to his campaign.

Nieto can not run for re-election, as Mexico's constitution limits presidents to a single six-year term.

Obrador said if he's elected Sunday, "the country will be cleansed" of corruption and he will "pull up by its roots the corrupt regime."

Other presidential contenders are Anaya of the National Action Party, Jose Antonio Meade of the Institutional Revolutionary Party and independent Jamie "El Bronco" Rodriguez.

A Gallup pollFriday showed most voters are dissatisfied with the country's political establishment, and those younger than 40 -- half of eligible Mexican voters -- say they're not confident in their present government.

The younger voters could reshape Mexican politics, with more than 3,000 positions at stake on the local and national levels. Nearly 90 million Mexican citizens are expected to vote Sunday.
