On the 27th, Lee Jun-seok, the leader of the reformist party in South Korea, engaged in a live-streamed debate on YouTube with Jeon Han-gil, a far-right YouTuber and former history instructor, focusing on the topic of election fraud. During the debate, which was heavily viewed with simultaneous viewers exceeding 300,000, Lee challenged Jeon's claims by demanding specific evidence for his unfounded allegations of election fraud. Jeon maintained that election fraud had been ongoing and insisted on investigating the election management committee's servers.

One particularly outrageous claim made by Jeon was that election fraud in South Korea has been prevalent since World War II, suggesting that a secret project started during the war laid the groundwork for a fraudulent electoral system. He mentioned historical figures like Kim Dae-jung, linking them to this supposed conspiracy. In response, Lee pointed out the absurdity of implicating a politician who had faced numerous electoral defeats in such a conspiracy, highlighting the ridiculous nature of Jeon's arguments.

The debate highlighted the ongoing tensions and divisions within South Korean politics regarding allegations of election integrity, particularly in the context of the 2020 parliamentary elections, which Jeon referred to while citing discrepancies in voting numbers as evidence of fraud. Lee's counterarguments underscored the lack of credible evidence surrounding these claims, thereby framing the discussion around the significance of substantiated allegations in politics and the potential ramifications of unfounded conspiracies on democratic processes.
