Even though he is detained in The Hague, former Philippine President Rodrigo Duterte was among candidates who vied for some 18,000 national and local seats in Monday’s midterm elections that analysts say will decide if he and his family continue to hold political power.

Duterte has been in custody of the International Criminal Court since March, awaiting trial for alleged crimes against humanity over a brutal war on illegal drugs that has left thousands of suspects dead during his 2016-2022 presidency. It hasn’t stopped him from running for mayor of his southern Davao city stronghold.

Under Philippine law, candidates facing criminal charges, including those in detention, can run for office unless they have been convicted and have exhausted all appeals.

Duterte is widely expected to win as Davao mayor, a position he held for over two decades before becoming president. He had received half a million votes, against 60,000 for his closest rival, according to a partial and unofficial count of 62% of the votes, CBS News partner BBC reported.

It’s less clear how Duterte can practically serve as mayor from behind bars.

Over 68 million Filipinos were registered to vote Monday for half of the 24-member Senate, all the 317 seats in the House of Representatives and various positions in provinces, cities and municipalities.

Polls closed at 7 p.m. local time, and unofficial results started to be reported a few hours later. Official results would be announced within a week.

The spotlight is on the race for the Senate that could determine the political future of Duterte’s daughter, Vice President Sara Duterte.

She faces an impeachment trial in the Senate in July over accusations of plotting to assassinate President Ferdinand Marcos Jr. and corruption involving her office’s intelligence funds. She has denied the allegations, saying they were spread by her political opponents to destroy her.

Sara Duterte is considered a strong contender for the 2028 presidential race. But if convicted by the Senate, she will be removed as vice president and disqualified from holding public office. To be acquitted, she needs at least nine of the 24 senators to vote in her favor.

“The 2025 midterm elections will be crucial because the results will set the pace for what will happen next, which family or faction will dominate the elections in 2028,” said Maria Ela Atienza, a political science professor at the University of the Philippines.

If Sara Duterte is convicted in the impeachment trial, it could signal the end of the Duterte family holding key positions in the country, she said. Other family members running in the election include Rodrigo Duterte’s youngest son, Sebastian, the incumbent mayor of Davao, who is now running for vice mayor and widely expected to win. The partial and unofficial count also put Sebastian in the lead, BBC reported.

Rodrigo Duterte’s eldest son Paolo is seeking reelection as a member of the House of Representatives. Two grandsons are also running in local races.

The impeachment and Rodrigo Duterte’s arrest and transfer to the tribunal in The Hague came after Marcos and Sara Duterte’s ties unraveled over political differences and their competing ambitions.

Earlier Monday, Sara Duterte voted in Davao while Marcos cast his ballot in his northern hometown, Batac City.

She told reporters after casting her ballot she would accept the will of the electorate if candidates she backed did not win.

Speaking about her father’s expected win: “Definitely, he will not be here, our expectation is the vice mayor (Sebastian) will be the acting mayor,” she said.

Marcos, in a video message on election eve, had urged Filipinos to vote and make their voice heard.

Her father’s spiritual adviser and close political ally, televangelist Apollo Quiboloy, is also running for a Senate seat despite being detained on charges of sexual abuse and human trafficking. He is also wanted in the U.S. on similar charges.

Voting was marred by pockets of violence. In Silay City in central Philippines, police reported that two people died and seven others were hurt in a shooting. In the southern New Corella municipality, supporters of two candidates vying for mayor engaged in a gunfight, leaving two dead and two wounded. In southern Basilan, seven people were killed in suspected election-related shootings. Several others were also injured in shootings in other parts of the country.

Fights between supporters of rival candidates also delayed balloting in some constituencies. In Manila, some voters complained their names were missing from the list in their precinct. Others grumbled about the long queue in stifling heat.

Voter Reymark Marquez said the Marcos-Duterte team that won in 2022 failed to deliver on promises. He said the midterm elections are “beyond Duterte versus Marcos but about choosing the right leaders.”

“I think what is at stake in this election is the future of the next generation,” Diana Joy Acosta, a 32-year-old new mother, said after casting her vote in a school in metropolitan Manila’s Mandaluyong City. For her baby’s future, she hopes for an end to corruption and the election of politicians with integrity.
