Eunpyeong B

Throughout its history, Eunpyeong B has elected members of liberal, centrist, and conservative political parties to represent the constituency. Despite conservative politician Lee Jae-oh being elected a total of five times in Eunpyeong B, in recent years, the liberal Democratic Party has been dominant in the constituency.^[1]

Deputy Speaker of the National Assembly Kim Jae-kwang of the centre-right Reunification Democratic Party was the first member to represent the constituency.^[2] He was succeeded by Lee Won-hyung of the centre-left Democratic Party who won in the 1992 election.^[3] Lee Jae-oh made his debut in this election as the left-wing Popular Party candidate.^[4] Lee Jae-oh won the following election held in 1996 as a member of the centre-right New Korea Party, defeating incumbent Lee Won-hyung by over eight points.^[5][6] Lee comfortably won re-election in 2000 with 51% of the vote and narrowly won re-election in 2004 with 45.25% of the vote against Uri Party candidate Song Mi-hwa who received 43.07% of the vote.^[7] However, Lee was defeated by Moon Kook-hyun of the centrist reformist Creative Korea Party by a margin of over eleven points.^[8][9]

On October 22, 2009, Moon Kook-hyun lost his seat after he was found guilty of violating South Korean election law; specifically the political funds act.^[10][11][12] Accordingly, a by-election for the constituency was held in 2010 which saw the constituency's former member Lee Jae-oh of the conservative Grand National Party win in a landslide, securing 58.33% of the vote.^[13][14][15] In the 2012 election, Lee narrowly won re-election by a margin 1.14% against unified opposition candidate Cheon Ho-sun of the centre-left Unified Progressive Party.^[16]

Ahead of the 2016 South Korean election, incumbent Lee Jae-oh was not re-nominated as the Saenuri Party's candidate for Eunpyeong B. This move came as the Saenuri Party's pro-Park Geun-hye faction grew influential within the party and denied renomination for many party members considered to be anti-Park or pro-Lee Myung-bak.^[17][18] In response to this, Lee left the Saenuri Party on March 23, 2016, and announced his intention to run as an independent candidate on the following day.^[19][20][21] The Saenuri Party decided not to nominate a candidate in the Eunpyeong B constituency on March 28, 2016.^[22][23] Despite this, Lee Jae-oh failed to win re-election, being defeated by Kang Byung-won of the liberal Democratic Party who won with 36.74% of the vote.^[24] Kang won re-election in 2020, garnering 57.41% of the vote.^[25] Kang was not re-nominated as the Democratic Party's candidate ahead of the 2024 election after being defeated by Kim Woo-young in a party primary.^[26][27] Kim won the general election with 56.95% of the vote, defeating People Power Party challenger Chang Seong-ho by a wide margin.^[28]

The constituency encompasses the neighborhoods of Gusan-dong, Daejo-dong, Jingwan-dong, Bulgwang-dong, and Galhyeon-dong. The constituency is bordered Goyang B to the north and west, Eunpyeong A to the south, and Jongno to the east.^[29]
