Ballot boxing Stage set for a battle of the political dynasties

Former Philippine president Rodrigo Duterte, 79, returned to politics last week when he registered to run as mayor in his family's stronghold, Davao city.

It places two of the country's most powerful political families, the Dutertes and the Marcoses, in an epic struggle for power.

For the Dutertes, it could prove a battle for survival. Rodrigo Duterte is facing an investigation by the international criminal court (ICC) for crimes against humanity over his war on drugs, and the family needs political clout and powerful friends.

Next year's midterm elections, scheduled for May, in which thousands of regional and city seats are to be contested - as well as 317 Congress seats and 12 senate positions will prove a broader test of the Dutertes' relevance.

For President Marcos Jr, son and namesake of the late dictator Ferdinand Marcos Sr, the elections will be crucial to cementing his legacy before he reaches the end of his single six-year term limit. Both families are already eyeing the 2028 presidential election. The vote could have major implications for the country's foreign policy, which under Marcos Jr has become more closely aligned with the US.
