More than 54 million Filipinos will vote for a new president, vice president, and about 18,000 lawmakers and local government officials in elections that happen every six years. “After deep soul searching, broad consultation and fervent prayers, I am accepting the challenge to run as vice president of Secretary Mar Roxas,” Leni Robredo told a cheering crowd of supporters in Manila, referring to former Interior Minister Manuel Roxas. Investors are closely watching the elections, fearing the political succession in one of Asia's fastest growing economies could derail gains made during Aquino's rule. Aquino has endorsed Roxas, the grandson of the country's first post-war president, to lead the ruling party into the polls and Robredo, a 51-year-old lawyer who won a seat in Congress in 2013, should boost the credibility of the ticket, analysts said. While Roxas' popularity ratings has jumped, according to the latest surveys, he is still in third place, trailing a novice senator, Grace Poe, and the incumbent vice president, Jejomar Binay. Analysts say Robredo brings a feeling of warmth and accessibility to Roxas' image as a straightforward, technocrat. Robredo has earned a reputation as a lawyer who helps poor farmers and fishermen and for being a steadfast opponent of corruption. Her late husband, Jesse Robredo, was interior minister when he was killed in a plane crash in 2012. “I am offering my whole self to our countrymen, especially those wearing flip-flops out in the streets, at the bottom, and at the edges of our society,” Robredo told the crowd, echoing her husband's crusade as a champion of the poor. Under Aquino, the Philippines has seen economic growth of more than 6 percent on average, its best 5-year record in four decades. The president, who is limited by the constitution to a single term, has also battled to rein in corruption. “Investors are looking for a continuation of the overall thrusts of the administration but with more attention to actual performance,” Steve Rood of Asia Foundation said. — Reuters
