His support plunged after an edited video circulated last September suggesting Purnama had mocked a verse in the Koran used by his opponents to argue Muslims should not vote for a person holding different religious beliefs. Amid two rallies last year that drew hundreds of thousands of protesters, Purnama was charged with blasphemy, forcing him to make regular appearances in court during the campaign. The hardline Islamists behind the rallies - led by the Islamic Defenders Front (FPI), a group known for attacks on religious minorities and extorting money from nightclubs -were cultivated by Purnama's rivals. Baswedan was accused of betraying his moderate Islamic roots when he met and sang with FPI leader Habib Rizieq, who was twice imprisoned for inciting violence in 2003 and 2008. Purnama recovered to win the first round on Feb. 15 with 43 percent of the vote, compared to 40 percent ข่าวด่วน เดลินิวส์ for Baswedan and 17 percent for Agus Yudhoyono, son of former president Susilo Bambang Yudhoyono, who drew support from conservative Muslims.

However, political analyst Tobias Basuki also saw risks for the national government and its reform agenda if Baswedan won, given plans by his political patron Prabowo Subianto to challenge Widodo in the 2019 presidential poll. Baswedan was Widodo's campaign manager in the 2014 presidential election, when he beat Subianto.
