BACOOR, Philippines — In a packed basketball arena in the province of Cavite, a half-hour’s drive south of the congested capital, Manila, Senator Grace Poe made her pitch to lead the Philippines as the country’s next president. “There is a long history of Cavitenos watching movies of my father and they remember that,” she said, referring to her famous adoptive father, the late film actor Ferdinand Poe, who ran unsuccessfully for president in 2004. Rather than featuring established, ideologically-driven political parties with slick campaign machines, Philippine elections are dominated by political dynasties, with a list of household names decorated with a smattering of celebrities, be they TV stars or sports icons such as world champion boxer Manny Pacquaio, who is running for a senate seat. Poe, with her cinema star father, has the background to match, and is not afraid to play it up in the quest for an edge in this close-run race.
