Jakarta, Indonesia (CNN) -- Millions of Indonesians cast their ballot for their next president in a neck-and-neck race between Joko "Jokowi" Widodo, a former furniture businessman who has drawn comparisons to U.S. President Barack Obama, and Prabowo Subianto, a well-connected former military man. Official results may take two to three weeks. Unofficial quick counts showed a slight edge for Widodo. One survey group, Lingkaran Survei Indonesia, showed 53.3% for Widodo and 46.7% for Prabowo with 99% of its data, and another group, Center for Strategic International Studies reported 52% for Widodo over 48% for Prabowo, with 95% of its data. Another independent survey group, Saiful Mujani Research and Consulting indicated 52-53% for Jokowi over Prabowo's 46% with 99% of data.
