Indonesia's presidential election is set for Wednesday. Incumbent Joko Widodo is not allowed to run again, so the country with the fourth largest population will usher in a new leader for the first time in about a decade.

It's a three-way race between Anies Baswedan, who served as governor of Jakarta for 5 years, Prabowo Subianto, who currently serves as defense minister, and Ganjar Pranowo, who previously served as the governor of Central Java province for 10 years. They are all campaigning with their own running mates, one of whom will become vice president.

The latest opinion poll shows Prabowo and Joko's son, Gibran Rakabuming Raka, leading with a support rate of more than 51 percent.

Prabowo is seen as Joko's natural successor. The incumbent president initially said he would be neutral, but local media reported he has moved to expand support for Prabowo by announcing cash assistance mainly for the country's poor ahead of the election day.

This election is called the world's largest direct vote to choose a leader, with more than 200 million eligible voters. A candidate will be elected president if they get more than half of the votes on Wednesday. Otherwise, there will be a runoff in June.
