Debate format

Just like the first and second rounds, the third and fourth Harapan 2019 debates will follow a "town hall" format. This will allow candidates to share their views on pressing national issues laid to them by Filipino public.

The first run of Harapan 2019 last February 17 made rounds online as it topped local and international trending lists on social media.
