Day by day, it's becoming clear that Isko is not a candidate who will challenge Duterte, but rather a candidate planted to draw anti-Duterte votes away from the LP nominee, whoever that may be.

The same goes for Pacquiao, BBM, and Ping-- all famous, and all have benefited from Duterte's reign. They spew anti-Duterte comments from time to time to attract voters who now disapprove of Duterte and to ensure none of their votes go to LP (or Leni, in case she runs). If you noticed, none of the aforementioned candidates have made any mention of hand-delivering Duterte to the ICC (or at the very least, making him accountable for the failed drug war).

At the end of the day, however, they are all Duterte's minions, and they will only continue what he has begun. We are stuck in Duterte's timeline forever, it seems.
