The president, Susilo Bambang Yudhoyono, has failed to boost his flagging popularity ratings. According to a survey conducted in December 2010 by a local organisation, the Indonesian Survey Institute (LSI), Mr Yudhoyono's approval rating stood at 63%, up from 62% in the previous survey, which was conducted in October, but still much lower than the high of 85% recorded after he was re-elected in July 2009. Respondents cited rising food prices and high unemployment, as well as a waning commitment to fighting corruption, as the reasons for their growing disenchantment with his leadership. Public approval of official anti-corruption measures fell to 51%, down from 84% in July 2009, while the government's efforts to control prices, eliminate poverty and create jobs received approval ratings of 35%, 31% and 27% respectively, suggesting that the benefits of the strong economic growth recorded in recent years have not been distributed evenly. The LSI also found that Mr Yudhoyono's Democratic Party (PD) remained the most popular political party, with the support of 21% of respondents. Its major rivals, by contrast, remain moribund. The main opposition party, the Indonesian Democratic Party of Struggle (PDI-P), recorded support from 14% of respondents, with the Golkar party trailing further behind, at 12%. Smaller Islamic parties, including the Prosperous Justice Party (PKS) and the National Mandate Party (PAN), are failing to make inroads into the support bases of the three main secular-nationalist parties. However, the most striking finding of the survey was the large number of undecided voters, at 30% of respondents, many of whom expressed an unfavourable view of all parties.
