In a recent video, author Yu Simin uses a Venn diagram to analyze the support base of President Lee Jae-myung, dividing supporters into three distinct groups. The first group, A, seeks 'values', while group B focuses on 'interests', and group C finds itself at the intersection of both, wanting both values and interests. Yu points out that during periods of high approval ratings for the president, groups B and C appear larger, while A seems smaller. However, he emphasizes that group A is the core of the Democratic Party's support base, remaining loyal even during crises, unlike group B, which tends to abandon the president as popularity wanes, an occurrence seen with past presidents Roh Moo-hyun and Moon Jae-in.

Yu's analysis has quickly gained traction on social media platforms, particularly among pro-government supporters. They have praised him for his insights, suggesting that his assessment has provided them with clarity regarding the 'New Lee Jae-myung' phenomenon, alleviating previously uncomfortable feelings about their support. However, there are criticisms of Yu's method of categorizing traditional and new supporters into 'value-seeking' and 'interest-seeking' groups, as it reflects a strong subjective bias. The dichotomy he presents of 'value versus interest' implies a moral judgment, suggesting that 'values' are public and noble, while 'interests' are seen as personal and potentially self-serving, which raises questions about the neutrality of his analysis.
