Results of quick counts conducted by the Indonesia Survey Institute (LSI) at polling stations across Bali showed the resort island remains the traditional bastion of the Indonesian Democratic Party of Struggle (PDI-P).
The party secured 44.5 percent of votes for seats at the House of Representatives.
Surprisingly, the Golkar Party, which for long had been the second most popular political power in Bali, succumbed to the meteoric rise of the Democratic Party.
Golkar only garnered 16 percent of votes while the Democratic Party notched up a considerable 20 percent.
In distance fourth place was the People's Conscience Party (Hanura) with 3.4 percent, followed closely by the Great Indonesia Movement Party (Gerindra) with 3.1 percent.
"The quick counts are based on data from 33 sample polling stations with a 4 percent margin of error," LSI Bali coordinator Bodrek Arsana said Friday.
Based on those results, Bodrek predicted the PDI-P would get five House seats, while Golkar and the Democratic Party would each get two.
In the 2004 elections, the PDI-P secured five House seats, followed by Golkar with two seats, while the Democratic Party got one seat.
PDI-P Bali campaign team head Adi Wiryatama expressed satisfaction with the poll results.
"We were aware many people predicted the PDI-P would get fewer votes, however we were also convinced the PDI-P would secure a similar number of seats at the House," he said.
Golkar's Bali chief, Nyoman Sugawa Korry, said the party's dwindling public support was a nationwide phenomenon, before hurriedly dismissing the quick count results.
"There is a strong attraction to the Democratic Party among the public," he said.
He added the fact that many Golkar members had jumped ship to new parties such as Gerindra and Hanura had contributed to the reduced votes.
The secretary of the Democratic Party's Bali campaign team, Gede Pasek Suardika, said the results reflected the public's growing trust in the leadership of Susilo Bambang Yudhoyono and in the party itself.
