The article discusses the challenges faced by Jang Dong-hyuk, the leader of the South Korean People Power Party, as he tries to revitalize the party's popularity amid declining support ahead of local elections. The metaphor of a box of moldy tangerines illustrates how neglecting internal issues can lead to broader negative consequences for the party, paralleling how rotten tangerines can ruin the entire box if not removed promptly. Jang has undertaken various public engagements and events, yet public interest has waned, as evidenced by low approval ratings for the party.

Furthermore, the article critiques Jang's leadership style and actions since becoming party chairman in August of last year, implying that despite his numerous attempts to engage the public through protests and community service, these efforts have not translated into increased support from voters. His initiatives such as a significant hunger strike and various public appearances have not captured the attention of a disinterested public, leading to the feeling that his leadership is ineffective in addressing the core issues within the party.

The text also points out critical decisions the party failed to make regarding former President Yoon Suk-yeol's actions, suggesting that active steps could have led to a strategic purging of factions within the party that are deemed detrimental. The author argues that without decisive action to ‘pick out the rotten tangerines,’ the party will continue to struggle, especially as they face challenges like impeachment proceedings against former leaders who are still influential in the party. The overarching theme displays a critical perspective of the current state of leadership within the People Power Party and its future ahead of key elections.
