The economy is one of the biggest issues for world’s biggest Muslim-majority country. Opinion polls put Mr Widodo at the forefront by double-digits, but many dispute these results. If Mr Subianto wins the election, it would cause a brief slump in Indonesia markets, according too analysts.
Kevin O’Rourke, a political analyst and author of Reformasi Weekly, said in the Indonesia-focused newsletter last week: “In a scenario in which Widodo wins by an unexpectedly narrow margin, large and prolonged protests in Jakarta would elevate tensions and pressure the currency.”
While most polls have put the president ahead, they could not be taken for granted, a senior government official said.
The official said: ”Absolutely everybody is flying blind because we don’t know how far the opinion polls can be respected.”
During the campaign, Mr Widodo has cited his successes with tackling inequality and poverty in Southeast Asia’s biggest economy.
He has invested in infrastructure and over the weekend he stated his opponents do not understand macroeconomics.
Mr Subianto has promised to boost the economy by slashing taxes up to eight percentage point and to focus on infrastructure.
He has also attacked his opponent of getting too close to China, something Indonesians are wary of.
Beijing has already been investing in projects in Indonesia and Mr Widodo wants to continue such a relationship.
Mr Subianto has accused said Mr Widodo has gone too soft on China by allowing millions of Chinese workers into the country to work on Chinese-funded projects.
He has pledged to review all of Beijing’s infrastructure’s projects if he gets elected.
Indonesians go to the polls on April 17.
Initial results will trickle in within hours after the polls close, but it will take a few weeks before the final result is declared.
