a referendum on Lee's presidency. The opposition coalition endeavored to depict the ruling party as unsocial and favoring the rich, while promising to create jobs. The incumbent government emphasised the threat of North Korea and made the case for continuing their hard line towards the northern neighbour and maintaining a close alliance with the United States. They accused the opposition of jeopardising the free trade agreement with the U.S. The DUP had demanded renegotiation of the treaty and threatened to cancel it in case of the United States' refusal to negotiate. The international media highlighted the candidacy of Cho Myung-chul, a professor who defected from North Korea in 1994. In its newspaper Rodong Sinmun, the North Korean Workers' Party called on the electorate to vote out the incumbent government: "Young voters, students and people must deliver a crushing defeat to the traitors."

The presidential office published an analysis stating that 84% of the recorded incidents had taken place under the previous administration of Roh Moo-hyun.

By region The result showed considerable regional variations. The DUP and its coalition partner the UPP made significant gains in the north-west of the country, winning a combined total of 26 new seats in Seoul, four in Incheon and 14 in suburban Gyeonggi-do. Altogether the DUP-UPP
