First-Ever 20% Party Member Vote... The Rule Born from the Aftermath of Choo Mi-ae’s Defeat

Rising Influence of Voting Members Becomes the "Eye of the Storm" That Could Sway the 80% Lawmaker Vote

Final Selection to Be Decided by Party Member Vote on the 11th–12th and Lawmaker Vote on the 13th

The race for the Speaker of the second half of the 22nd National Assembly is heating up. This comes as public sentiment among supporters for Democratic Party lawmaker Park Ji-won, who represents Haenam, Wando, and Jindo in South Jeolla Province, has reached an unprecedented high.


For the first time in history, the rule incorporating a “20% reflection of party member votes” is not merely a supplementary measure; the political sphere is paying close attention to whether this will serve as the so-called “paradox of 20%,” strongly influencing the voting decisions of current lawmakers who account for the remaining 80% of the weight.

Recent poll results clearly show this concentration of party sentiment. In a survey commissioned by Straight News and conducted by JoWon C&I, Assemblyman Park Ji-won recorded overwhelming support from Democratic Party supporters, surpassing 52%.


The figure, which had hovered around 44–45%, suddenly jumped above the majority threshold of 50%. Political observers interpret this not simply as a rise in name recognition, but as a strong signal of consolidation among party members with voting rights.

The Painful Lesson of 'Choo Mi-ae’s Defeat' Led to the 20% Party Member Rule

The biggest variable in this race for Speaker is undoubtedly the “20% party member vote.” This is the first time in the history of South Korea’s constitutional government that the voices of party members are directly reflected in the selection of the National Assembly Speaker, across both the ruling and opposition parties.


This 20% figure has its roots in a painful historical experience for the Democratic Party. The catalyst was the 2024 race for Speaker. At that time, Assemblywoman Choo Mi-ae, who enjoyed an overwhelming lead in the party member poll, was unexpectedly defeated by Assemblyman Woo Won-shik in the lawmakers’ vote. The backlash from party members with voting rights was immediate and intense.


With protests such as, “I cannot remain in this party,” more than 20,000 members left in a wave of resignations. This massive anger and the ensuing repercussions ultimately became the driving force behind the unprecedented institution of the “20% party member reflection” rule. Since then, the status of party members with voting rights within the Democratic Party has risen dramatically.


Party leader Jeong Cheong-rae secured his position at the party convention based on these party member votes, and the “one person, one vote” system was subsequently adopted, giving equal weight to the votes of delegates and party members. Currently, the Democratic Party’s core decision-making processes—including nominations for president, governors, and lawmakers—have been transformed so that party members with voting rights now hold more than 50% of the voting weight.

A Structure Where 20% Sways 80%... Lawmakers' Sensitivity to Voter Sentiment

Ultimately, the key lies in the choices of the incumbent lawmakers, who hold 80% of the decision-making power. From the perspective of these lawmakers—who are sensitive to the voting intentions of party members holding future nomination rights and influence over internal party sentiment—the fact that a particular candidate has secured overwhelming support of over 50% among party members imposes significant political pressure.


In this context, the fact that Assemblyman Park Ji-won has secured 52% support from the party’s base is highly significant. It indicates a structural shift, where the 20% party member sentiment is effectively driving the 80% sentiment among lawmakers.



The Democratic Party will conduct an online vote of party members with voting rights from May 11 to 12, and on May 13, the final candidate for the second half Speaker will be confirmed by an on-site vote of lawmakers. Will the “paradox” of the 20% swaying the 80% become a reality? This outcome is expected to be the first response to increasingly strong demands for party member democracy.
