Eunpyeong A

Since its establishment, Eunpyeong A has elected members of the Democratic Party and predecessor parties in all but two elections and is thus regarded as a stronghold for the Democratic Party.^[1][2][3]

Oh Yu-bang of the right-wing Democratic Justice Party was the first member to represent the constituency, narrowly defeating Cho Dong-hoe of the Peace Democratic Party.^[4] Oh was succeeded by Son Sae-il of the centrist-liberal Democratic Party after losing re-election in the 1992 election.^[5] Son won re-election in 1996, defeating Kang In-sop of the centre-right Grand National Party.^[6] Son was defeated by Kang In-sop in the following election by a margin of around 5,000 votes, marking the last time a conservative party candidate won in Eunpyeong A.^[7] In the 2004 election, Lee Mi-kyung of the liberal Uri Party won the seat, securing 51.79% of the vote.^[8] Lee won re-election in 2008 and 2012, receiving 45.82 and 49.05% of the vote respectively.^[9][10]

Ahead of the 2016 South Korean legislative election, the Democratic Party then led by Kim Chong-in, did not re-nominate incumbent Lee Mi-kyung for the Eunpyeong A constituency.^[11][12] The party instead nominated lawyer Park Joo-min as its candidate on March 20, 2016.^[13][14] Park went on to win the general election with 54.93% of the vote, defeating opponents Choi Hong-jae and Choi Sang-hyeon of the Saenuri Party and Labor Party respectively.^[15][16] Park won re-election in a landslide in 2020, securing 64.29% of the vote and defeating United Future Party opponent Hong In-jung.^[17] The 2024 election saw rematch between incumbent Park Joo-min and Hong In-jung; Park won re-election with 60.78% of the vote.^[18][19]
