In the Philippines, the 24-member Senate acts as the jury in any impeachment trial, making the midterms even more consequential in determining Sara Duterte's political future. Sara, who has denied wrongdoing, has responded to her impeachment with defiance, asking the Supreme Court to nullify the complaint against her.

The outcome could shape the country's strategic positioning over the remaining half of President Ferdinand Marcos Jr's six-year term.

The Philippines began voting on Monday in midterm elections that could decide the fate of impeached Vice President Sara Duterte, whose feud with President Ferdinand Marcos Jr. comes as the Southeast Asian nation grapples with both the global trade war and growing tensions with China.
