Star Metro - Incumbent Noboa leads Ecuador presidential runoff

With nearly half the votes counted, the 37-year-old president led his charismatic leftist rival Luisa Gonzalez 57 percent to 43 percent, according to the official tally.

Millions of votes have still to be counted, so the race could yet narrow. But Noboa appeared buoyed as the polls closed.

"Thank you to all the Ecuadorians who bravely went to the polls. Today will be a great day," he posted on social media.

Noboa narrowly won February's first round, but not by enough to avoid another duel against a resurgent Luisa Gonzalez, who is bidding to become Ecuador's first woman president.

The campaigns were dominated by anger over the lackluster economy and cartel violence that has transformed Ecuador from one of the safest countries in Latin America into the most deadly.

In the volcano-ringed capital Quito, voters wrapped up against the Andean chill and flocked to the polling stations.

"I think Ecuador is divided, but I think we all understand we are in a situation where we have to unite, whoever is leading the government," said 21-year-old architecture student Camila Medina.

In total, about 13.7 million Ecuadorans were obliged to vote.

On the eve of the ballot, Noboa declared a 60-day state of emergency in the capital and several provinces, underscoring the tense state of affairs.

This once-peaceful nation averaged a killing every hour at the start of the year, as cartels vied for control over cocaine routes that pass through Ecuador's ports.

Noboa, the guitar-strumming son of a billionaire banana magnate, has staked his political fortunes on "iron fist" security policies designed to snuff out the gangs.

He has deployed the military to the streets, captured drug capos and invited the United States to send special forces.

By contrast, 47-year-old single mother Gonzalez has pitched herself as a political everywoman, born to a humble family and laser-focused on improving the lot of poor Ecuadorans.

She may have a growing constituency. Rampant bloodshed has spooked investors and tourists alike, fueling economic malaise and swelling the ranks of Ecuador's poor to 28 percent of the population.

Ecuador faces two very different paths depending on which candidate wins.

A Noboa win would likely see him double down on hardline security policies and further nurture a budding bromance with US President Donald Trump.

If Gonzalez wins, it would signal a sharp shift to the left and a likely cooling of Ecuador's relations with the United States.

Gonzalez is closely allied with ex-president Rafael Correa, who delighted in lobbing barbs at Washington during his decade in office.

He now lives in exile in Belgium, avoiding a corruption conviction he claims is politically motivated. He remains a deeply polarizing figure in his homeland.

"We are going to make history for Ecuador!" Gonzalez told supporters while voting in her hometown near the Pacific coast. "We are ready to defend democracy."
