Voting begins in Mexican presidential election: official

Mexicans have started voting on Sunday in a presidential election marred by cartel violence and deep division.

Polls opened at 08:00 am (1300 GMT) in the south eastern state of Quintana Roo and some areas near the US border, with other regions in different time zones due to follow later.

Ruling party candidate Claudia Sheinbaum, a former Mexico City mayor and a scientist by training, had a 17 percentage point lead over her main opposition rival Xochitl Galvez on the eve of the vote.

Centrist Jorge Alvarez Maynez was trailing far behind as a particularly violent campaign season marked by a string of candidate murders drew to an end.

It means that, barring a huge surprise, a woman is almost certain to break the highest political glass ceiling in Mexico, where around 10 women or girls are murdered every day.

That prospect motivates other women to succeed and to think "yes, you can," said Blanca Sosa, a 31-year-old store worker in Mexico City.

She expects Sheinbaum to continue the "good things" done by outgoing President Andres Manuel Lopez Obrador, such as pensions for the elderly and an increased minimum wage.

Ricardo Sanchez, however, said he planned to vote for Galvez because of her "business vision".

Lopez Obrador's " policy of putting the poor first is to ruin us all so that we're poor and then he gives to us," the 55-year-old businessman said in the northern city of Monterrey.

Sheinbaum, 61, owes much of her popularity to Lopez Obrador, a fellow leftist and mentor who has an approval rating of more than 60 percent but is only allowed to serve one term.

Blood-soaked campaign

Thousands of troops will be deployed to protect voters from ultra-violent drug cartels that have gone to extreme lengths to ensure their preferred candidates win.

More than two dozen aspiring local politicians have been murdered during the election process, according to official figures, in a nation where politics, crime and corruption are closely entangled.

In a sign of the difficulties of staging elections in cartel hotspots, voting was suspend ed in two southern municipalities because of violence, local authorities said Saturday.

"The fight against organised crime will be the biggest challenge for the next president," said Guadalupe Correa-Cabrera, a professor at George Mason University, in the United States.

Security was the weakest point of Lopez Obrador's administration, she told AFP.

Sheinbaum has pledged to continue the outgoing president's controversial "hugs not bullets" strategy of tackling crime at its roots.

Galvez has vowed a tougher approach to cartel-related violence, declaring "hugs for criminals are over."

More than 450,000 people have been murdered and tens of thousands have gone missing since the government deployed the army to fight drug trafficking in 2006.

The next president will also have to manage delicate relations with the neighboring United States, in particular the vexed issues of cross-border drug smuggling and migration.

As well as voting for a new president, Mexicans will choose members of Congress, several state governors and myriad local officials.

In total, more than 20,000 positions were being contested.
