열린우리당
Prior to the Uri Party's devastating defeat in regional elections held on May 31, 2006, Chung apologized for the party's "self-righteous attitude and inadequacy". The party failed to win in all but one area, while the opposition Grand National Party took 12 of the 16 key regional posts in the election. The Uri Party even lost in Daejeon, a city long considered a secure ruling-party stronghold.
