More than 18,000 government posts are up for grabs in elections in the Philippines on Monday.

President Rodrigo Duterte is not on the ballot, but the vote is widely viewed as a referendum on his controversial rule, which has entailed a brutal crackdown on drug crimes. Over 20,000 people have died in extrajudicial killings related to the drug war, according to opposition politicians cited by the Economist.

Duterte’s allies are expected to keep control of the country’s House of Representatives and gain seats in the Senate.

His daughter Sara Duterte has played a prominent role in the campaign, acting as kingmaker in many races, according to Reuters. She is currently mayor of Davao City, a post previously held by her father, and could follow in his footsteps to run for president in 2022.

In February, US Secretary of State Mike Pompeo met Rodrigo Duterte in Manila. The leaders discussed improving cooperation on regional security and counter-terrorism, according to the State Department.
