Senator Franklin Drilon (Senate of the Philippines / MANILA BULLETIN) Luzon, which is the most populated among the country’s three main islands, has none while Visayas has one- Ma. Rowena Amelia V. Guanzon. The seventh post as commissioner is not still filled up. There is an ‘’uneven representation,’’ Drilon lamented. Three of the five are residents of Davao, the home province of President Duterte while the two others are in other parts of Mindanao. One of them is Comelec Chairman Sheriff M. Abas. Aside from Guanzon, the other Comelec commissioners are Socorro B. Inting, Marlon S. Casquejo, Antonio T. Kho Jr. and Aimee P. Ferolino-Ampoloquio.
