One online meme showed Mr Widodo sitting on the coveted Iron Throne. But this isn’t the first time the hit US show has been compared to politics in Indonesia. The president used references from the show to explain risks facing the global economy in a speech last October.
He said: “All these troubles in the world economy, are enough to make us feel like saying: ‘Winter is Coming’.
“The situation could be more critical compared to the global financial crisis 10 years ago.
“Lately it feels like the relations among the major economies are becoming more and more like “Game of Thrones.
“Are we so busy fighting with each other and competing against each other that we fail to notice the things which are increasingly threatening, all of us alike, rich and poor, large and small.”
Mr Widodo touted his record on deregulation and improving infrastructure, calling it a first step to tackling inequality and poverty in Southeast Asia’s biggest economy.
A moderate Muslim from central Java, Mr Widodo had to burnish his Islamic credentials after smear campaigns and hoax stories accused him of being anti-Islam, a communist or too close to China, all politically damaging in Indonesia.
He picked Islamic cleric Amin, 76, as his running mate.
Prabowo, a former special forces commander who has links to some hardline Islamist groups, and his running mate, business entrepreneur Sandiaga Uno, say they will boost the economy by slashing taxes and cut food prices.
Political analyst Dewi Fortuna Anwar said the “instrumentalisation” of religion had become much more visible in Indonesian politics in recent years with both candidates trying to appeal to conservative Islamic groups.
Mr Widodo entered politics 14 years ago as a small-city mayor and is seeking re-election against former general Prabowo Subianto, who he narrowly defeated in the last election, in 2014.
Most opinion polls give Mr Widodo a double-digit lead, but the opposition says the race is much closer and Prabowo, who said he was optimistic about winning with a big margin.
Mr Widodo said he felt “relieved” after casting his ballot and displaying a finger dipped in indelible ink, part of the process of avoiding fraudulent voting.
