How do you organise free and fair elections in a sprawling developing country beset by political corruption, bureaucratic incompetence and organisational inefficiency? For Indonesia – and its 193 million voters – the answer lies in the vast number of polling stations, the use of a metal nail (not a pen or a machine) for voting, 1.6 million bottles of halal certified ink and the practice of counting votes in public. On April 17, the world’s third most populous democracy is holding simultaneous presidential and legislative elections for the first time. It will be world’s biggest direct presidential elections (because the US uses an electoral college) and one of the most complicated single-day elections in global history. By contrast, India, which is the world’s biggest democracy, is conducting its parliamentary elections through a rolling regional process over six weeks in April and May. As the Lowy Institute’s new infographic highlights, the scale of Indonesia’s electoral process is mind-boggling, with five separate elections at once, for the president, both houses of parliament, provincial legislatures and district/city councils. Altogether, there are more than 245,000 candidates running for more than 20,000 national and local legislative seats across hundreds of islands, in addition to the headline contest between President Joko Widodo and challenger Prabowo Subianto.
