MEXICO CITY -
Mexico's projected presidential winner Claudia Sheinbaum will become the first female president in the country's 200-year history.
Sheinbaum, the favored successor of outgoing President Andres Manuel Lopez Obrador, vowed to continue on the direction set by the populist leftist leader. But the cool-tempered scientist offers a sharp contrast in style -- and a break with Mexico's male-dominated political culture.
"I promise that I am not going to let you down," Sheinbaum said, greeting supports in Mexico City's colonial-era main plaza, the Zocalo.
The National Electoral Institute's president said Sheinbaum had between 58.3 per cent and 60.7 per cent of the vote, while opposition candidate Xochitl Galvez had between 26.6 per cent and 28.6 per cent and Jorge Alvarez Maynez had between 9.9 per cent and 10.8 per cent of the vote. Sheinbaum's Morena party was also projected to hold its majorities in both chambers of Congress.
The climate scientist and former Mexico City mayor said that her two competitors had called her and conceded her victory.
The official preliminary count put Sheinbaum 28 points ahead of Galvez with nearly 50 per cent of polling places reporting.
The fact that the two leading candidates were women had left little doubt that Mexico would make history Sunday.
"As I have said on other occasions, I do not arrive alone," Sheinbaum said shortly after her victory was confirmed. "We all arrived, with our heroines who gave us our homeland, with our mothers, our daughters and our granddaughters."
Sheinbaum will also be the first person from a Jewish background to lead the overwhelmingly Catholic country.
She will start her six-year term Oct. 1. Mexico's constitution does not allow reelection.
The leftist has said she believes the government has a strong role to play in addressing economic inequality and providing a sturdy social safety net, much like her political mentor.
Lopez Obrador's anointed successor, the 61-year-old Sheinbaum consistantly led in polls despite a spirited challenge from Galvez. This was the first time in Mexico that the two main opponents were women.
"Of course, I congratulate Claudia Sheinbaum with all my respect who ended up the winner by a wide margin," Lopez Obrador said shortly after the electoral authorities' announcement. "She is going to be Mexico's first (female) president in 200 years."
If the margin holds it would approach his landslide victory in 2018. Lopez Obrador won the presidency after two unsuccessful tries with 53.2 per cent of the votes, in a three-way race where National Action took 22.3 per cent and the Institutional Revolutionary Party took 16.5 per cent.
Still, Sheinbaum is unlikely to enjoy the kind of unquestioning devotion that Lopez Obrador has enjoyed.
In the Zocalo, Sheinbaum's win did not draw the kind of cheering, jubilant crowds that greeted Lopez Obrador's victory in 2018. Those present were enthusiastic, but comparatively few in number.
Sara Rios, 76, a retired literature professor at Mexico's National Autonomous University, celebrated after hearing that Galvez had conceded.
"The only way that we move forward is by working together," Rios said. "She is going to work to bring peace to the country, and is going to manage to advance, but it is a slow process."
Fernando Fernandez, a chef, 28, said he voted for Sheinbaum because of her ties to Lopez Obrador, using the president's initials, AMLO. But his highest hope is that Sheinbaum can "improve what AMLO couldn't do, the price of gasoline, crime and drug trafficking, which he didn't combat even though he had the power."
The main opposition candidate, Galvez, a tech entrepreneur and former senator, had promised a more aggressive approach toward organized crime.
In her concession speech, she said "I want to stress that my recognition (of Sheinbaum's victory) comes with a firm demand for results and solutions to the country's serious problems."
Lopez Obrador claims to have reduced historically high homicide levels by 20 per cent since he took office in December 2018. But that's largely a claim based on a questionable reading of statistics. The real homicide rate appears to have declined by only about 4 per cent in six years.
Julio Garcia, a Mexico City office worker, said he voted for the opposition because of crime. "They've robbed me twice at gunpoint. You have to change direction, change leadership," the 34-year-old said. "Continuing the same way, we're going to become Venezuela."
On the fringes of Mexico City in the neighbourhood of San Andres Totoltepec, 34-year-old homemaker Stephania Navarrete said she planned to vote for Sheinbaum despite her own doubts about Lopez Obrador and his party.
"Having a woman president, for me as a Mexican woman, it's going to be like before when for the simple fact that you say you are a woman you're limited to certain professions. Not anymore."
She said the social programs of Sheinbaum's mentor were crucial, but added that deterioration of cartel violence in the past few years was her primary concern in this election.
Nearly 100 million people were registered to vote and turnout appeared to be about 60 per cent, similar to earlier elections.
Voters were also electing governors in nine of the country's 32 states, and choosing candidates for both houses of Congress, thousands of mayorships and other local posts, in the biggest elections the nation has seen and ones that have been marked by violence.
The elections were widely seen as a referendum on Lopez Obrador, a populist who has expanded social programs but largely failed to reduce cartel violence in Mexico. His Morena party currently holds 23 of the 32 governorships and a simple majority of seats in both houses of Congress.
Sheinbaum promised to continue all of Lopez Obrador's policies, including a universal pension for the elderly and a program that pays youths to apprentice.
Just as the upcoming November rematch between U.S. President Joe Biden and former president Donald Trump has underscored deep divisions in the U.S., Sunday's election revealed how severely polarized public opinion is in Mexico over the direction of the country, including its security strategy and how to grow the economy.
