Jokowi's son will run for the seat Megawati's daughter holds

Kaesang Pangarep, the youngest son of former president Joko Widodo, told a party meeting in Solo on 25 July that he will stand for parliament in 2029 in Central Java V. That is the district Puan Maharani holds. She is the daughter of former president Megawati Sukarnoputri and one of the most senior figures in PDI-P, the party Megawati still leads. Kaesang chairs PSI, the small party his family has been building. The South China Morning Post reports that the choice of district is the point of the exercise.

Central Java V covers Solo, Boyolali, Klaten and Sukoharjo. Solo is where Jokowi was mayor and where his name still carries weight, and the district has been a PDI-P stronghold since 2009. Kaesang picked the one place where his father's popularity and Megawati's party machine have to meet head on. Marcus Mietzner of the Australian National University called it the boldest move yet in the growing fight between the two families.

Nobody has to lose outright. Indonesia elects several members from each district in proportion to the votes each party wins, so Kaesang and Puan can both end up in parliament. The real result is the size of the numbers. A big PSI vote in Solo would show that Jokowi can hand his popularity to his children; a weak one would show it stayed with him and left when he did. PDI-P has its own reason to care. It sits outside President Prabowo Subianto's governing coalition, and a poor showing on its home ground would raise questions about what the party is for now.

Why it matters

For voters in Solo, Klaten, Boyolali and Sukoharjo, this decides who represents them, and both candidates are running on a family name rather than a record. For everyone else it is a test of whether the Widodo family can keep a hold on national politics without the presidency, which shapes how open the 2029 race will be. Watch PSI's results in local votes before then, because that is where the machine will show if it works.
