Marcos' Grip on Power Shaken as Duterte Allies, Opposition Surge in Midterm Polls

Results Seen as a Protest Vote by Filipinos and a Rebuke to Status Quo

MANILA - Voters dealt President Ferdinand Marcos Jr. a stinging blow in the Philippines' midterm elections that weakened his grip on the Senate, while boosting Vice President Sara Duterte's allies just weeks before an impeachment trial against his deputy.

Early results also showed independent opposition candidates performing stronger than expected in the May 12 polls.

Some 68.43 million voters went to the polls to elect more than 18,000 officials nationwide to fill half of the 24-seat Senate, all 316 seats in the House of Representatives, and thousands of local posts—from mayors to governors and their deputies in every province, city, and town.

Partial, unofficial counts by 11:11 p.m., with 75.45 percent of results transmitted, showed Mr. Marcos' Alyansa Para sa Bagong Pilipinas (Alliance for a New Philippines) slate winning only six of the 12 contested Senate seats—well below the nine predicted in pre-election surveys.

Ms. Duterte's slate picked up five seats. Mr. Bong Go, a longtime aide to her father, former president Rodrigo Duterte, has clinched 25.6 million votes so far—the most number of votes among the candidates vying for one of 12 contested Senate seats.

One Senate seat was claimed by a candidate endorsed by both factions: Ms. Camille Villar, daughter of Filipino billionaire Manny Villar, who remained on Mr. Marcos' slate but aired campaign ads with Ms. Duterte in the final stretch of the campaign. As the votes were tallied, Ms. Villar was counted under both Mr. Marcos' and Ms. Duterte's victories.

But the strongest rebuke to the political status quo came from outside the Marcos-Duterte camps.
