The newly formed liberal Uri Party (Uri-dang or Our Party) gained support through its opposition to the impeachment of President Roh. It won 32 out of 49 seats in Seoul, 44 out of 62 in Incheon and Gyeonggi, confirming that a majority of voters supported the President Roh.

The conservative Grand National Party, which supported the impeachment of President Roh, suffered a loss of support, but won a majority in North Gyeongsang and South Gyeongsang regions and retained the 100 seats necessary to block constitutional changes.

The progressive, socialist Democratic Labor Party got 13.03% of vote share, but won only 10 out of 299 seats due to the FPTP system. However this was considered as a great triumph within political landscape of South Korea which is traditionally anti-communist and against left-wing policies. DLP also won two FPTP seats in Ulsan and Changwon based on labor movement.

The Millennium Democratic Party, formerly the major liberal party, was the second-largest party prior to the election but sustained the biggest loss in the backlash following its leading role in the impeachment of Roh, as much of its support shifted to the Uri Party.

The United Liberal Democrats, a conservative regional party based on North Chungcheong and South Chungcheong regions, lost support since its leader, Kim Jong-pil, did not contest the last presidential election.
