Davao

Even from his prison cell in The Hague, former President Duterte ran for mayor of Davao, and won easily, even though all voters got to see of him was a life-size cardboard cutout.

Much the same is true of the Dutertes in their stronghold in Davao at the other end of the country.

Dutertes have been mayors of Davao for 34 out of the last 37 years.

Duterte himself led Davao, a sprawling southern metropolis, for two decades before he was elected president in 2016.

Maintaining a political base in Davao city in the south is crucial for the Dutertes - it is where they get the most voter support.
