Guatemalans choose president amid distrust, flight to US Guatemalans headed to the polls Sunday to cast their vote for the next president, following an electoral process that generated widespread disillusion and distrust

GUATEMALA CITY -- Guatemalans voted for a new president Sunday following an electoral process that generated widespread disillusion and distrust, and came as tens of thousands were fleeing poverty and gang violence to seek a new life in the United States.

Marco René Cuellar, the first to vote at the Mixed Rural School in the municipality of Santa Catarina Pinula, said he hoped for the good faith of the winner because the country needed changes.

"There is a belief that instead of advancing in these four years of government, we've gone backward," said the 39-year-old, adding that the candidates had little to offer. "We've lost our way as a country, but we should not lose faith in the democratic process we have."

Voters are choosing between 19 candidates for a four-year presidential term that begins in January 2020. The winner needs an absolute majority, making an August runoff between the two top vote-getters likely. More than 8.1 million citizens of the Central American nation will also be eligible to vote for the vice president, congressional representatives and mayors.

The top five candidates for president are: former first lady Sandra Torres of the National Unity and Hope party, who is expected to finish first but without enough votes to win in the first round; former prison director and four-time presidential candidate Alejandro Eduardo Giammattei Falla; businessman Roberto Arzú; lawyer and journalist Edmond Auguste Mulet Lesieur; and Thelma Cabrera, the only indigenous candidate.

On Sunday, municipal officials and police stood guard as many waited in line to cast their ballot in an election dinged by threats of violence and possible fraud.

To the east of the capital, in the Zacapa department, voting stations didn't open in the San Jorge municipality after organizers were threatened with violence. More than 7,000 people were unable to cast votes there. Voting was also called off in Esquipulas Palo Gordo, near the border with Mexico in the San Marcos department, amid accusations of vote-buying.

The attorney general's office launched an investigation after a voter posted a video to social media showing how her ballot was allegedly already marked for Torres.

The campaign season was marked by a chaotic flurry of court rulings, shenanigans, illegal party-switching and allegations of malfeasance that torpedoed the runs of two of the three front-runners, including Chief Prosecutor Thelma Aldana.

Aldana gained international renown for leading crusading anti-corruption investigations in tandem with a U.N.-backed anti-graft commission operating in Guatemala, but was booted from the race on the grounds that she lacked a document certifying that she didn't have any outstanding accounts from her time overseeing a public budget as prosecutor.

Outgoing President Jimmy Morales, who is barred from seeking re-election, took office in 2016 promising to root out corruption after his predecessor was brought down by a probe led by the U.N.'s International Commission against Impunity in Guatemala, or CICIG. But Morales soon became a target of CICIG himself for alleged campaign finance violations, starting a bitter dispute with the agency in which he terminated its mandate.

Three of the last four elected presidents have been arrested post-presidency on charges of corruption.

A recent poll from CID Gallup Latinoamerica found that nearly a third of Guatemalan adults surveyed believe the election will be plagued by fraud. Another 20 percent said the election's legitimacy would be suspect because so many candidates were kept from running.

The current election marks the first time that Guatemalans can cast ballots from abroad: At least 60,000 are eligible to vote in Los Angeles, New York, Maryland and Washington, D.C., all home to large numbers of Guatemalan emigres.

Unemployment, violence, corruption, rising costs of living and the shoddy state of the country's highways are among top concerns for the country's electorate.

But Fernando Barrillas, 44-year-old Guatemalan citizen, said surging migration was also an issue for him.

"As long as the root causes that propel migration are not addressed, which are poverty and inequality, we will continue to remain without the best men and women, young people who they are the engine of the country," he said.

An estimated 1 percent of Guatemala's population of some 16 million people has left the country this year.
