A new survey on the popularity and electability of political parties in the country showed that more and more people were losing faith in Islamic parties.

Out of five Islam-based political parties in a survey by the Alvara Research Center conducted in July and August, none made it to the top five parties in the country in terms of popularity and electability.

"They are in the bottom of the list. Islamic parties are very weak and they continue to weaken," said Hasanuddin Ali, founder and president director of Alvara, in a press conference on Wednesday.

Hasanuddin attributed the low popularity and electability to several corruption cases implicating Islamic party figures and leaders, which caused voters from the middle-income group to lose confidence in religion-based parties.

"The track record and capacity of Muslim figures is also still low. No figure is considered eligible yet," Hasanuddin said.

The survey said the Prosperous Justice Party's (PKS) electability was 3.4 percent, the United Development Party (PPP) 2.2 percent, the National Mandate Party (PAN) 2.1 percent, the National Awakening Party (PKB) 1.7 percent and the Crescent Star Party (PBB) 0.1 percent.

Only former Supreme Court chief justice Mahfud MD, a member of the PKB, was eligible in terms of electability as a presidential candidate. Nonetheless, Mahfud has an eligibility rate of only 3.4 percent and electability of only 4 percent.

Siti Zuhro, an analyst from the Indonesian Institute of Sciences (LIPI), said that while an Islamic-based coalition would be a considerable force to be reckoned with, it would likely never materialize. "They just don't have a history of joining forces and standing behind a common candidate," she said.
