The new branding of the Indonesian Solidarity Party, with the full support of Joko Widodo, has the potential to overshadow the position of the Indonesian Democratic Party of Struggle (PDI-P). Their electoral track records demonstrate an electoral relationship between the two political parties. The political track records between the two parties are undeniable. Jokowi's presence as a former member of the Indonesian Democratic Party of Struggle (PDI-P) and former president is a variable that provides a "meeting point" between PDI-P and the Indonesian Solidarity Party (PSI). This is inextricably linked to the political reality that Jokowi is a figure closely associated with PSI. Since the 2019 election, PSI has been a strong supporter of Jokowi, and in the 2024 election, it even branded itself as Jokowi's party. This branding was promoted not only on social media but also in the real world, with campaign props featuring the PSI logo and Jokowi's photo. This move was intended to reinforce the message that the PSI is Jokowi's endorsed political party, especially since the party is led by his youngest son, Kaesang Pangarep. Jokowi conveyed this explicit and firm support at the PSI Congress in Surakarta in mid-July, where he declared his full support for the PSI in the 2029 elections. "I will fully support PSI. Therefore, I will work hard for PSI," Jokowi said, as quoted by Kompas.id (July 19, 2025). The results of this congress re-appointed Kaesang Pangarep as PSI Chairman for the 2025-2030 period. Kaesang officially joined PSI in September 2023, and just 60 hours after joining the party, he was officially inaugurated as PSI Chairman at the National Coffee Gathering (Kopdarnas) in Jakarta (Kompas, September 30, 2023). Since Kaesang's official appointment as chairman, Jokowi's name has been frequently linked to the PSI, and at its climax at its congress in mid-July, Jokowi explicitly affirmed his support for the party to pass the parliamentary threshold in the 2029 elections. According to election results, PSI has only participated in two elections: in 2019 and 2024. However, in both elections, the party failed to pass the 4 percent parliamentary threshold. In the 2019 election, PSI garnered 2,650,361 votes, equivalent to 1.89 percent of the national valid vote. Its vote share increased in the 2024 election to 4,260,169 votes, or 2.81 percent, but still fell short of the parliamentary threshold.
