20 vote-rich areas and their vice presidential bets

MANILA, Philippines — While Rodrigo Duterte has claimed a convincing lead to become presumptive president, the vice presidential race is far from over with the small margin of votes between the front-runner Maria Leonor "Leni" Robredo and rival Ferdinand "Bongbong" Marcos Jr.
