# Dobong B

Dobong B (Korean: 도봉구 을) is a constituency of the National Assembly of South Korea. The constituency consists of parts of Dobong District, Seoul. As of 2024, 136,197 eligible voters were registered in the constituency. The constituency was created in 1996 after being reorganized from the former Dobong B and Dobong C constituencies.

## History

Since its establishment, Dobong B has more often voted for centre-left, liberal parties to represent the constituency and is thus considered a stronghold for the Democratic Party.
Sul Hoon of the centrist-liberal National Congress for New Politics was the first member to represent the constituency, having narrowly beat out Paik Young-ki of the centre-right Grand National Party. Sul won re-election in 2000, once again defeating Paik. However, Sul did not run for re-election in 2004 after being indicted on falsely claiming that then presidential candidate Lee Hoi-chang had received $200,000 from businessman Choi Kyu-sun. Sul was succeeded by Yoo Ihn-tae of the liberal Uri Party, receiving 47.37% of the vote. Yoo unsuccessfully ran for re-election in 2008 and was defeated by Kim Seon-dong of the Grand National Party. A return match between Yoo and Kim was held in 2012 which saw Yoo win back the seat. Ahead of the 2016 South Korean legislative election, the Democratic Party "cut-off" Yoo from re-nomination, instead nominating lawyer Oh Gi-hyoung for the constituency. Kim Seon-dong of the conservative Saenuri Party emerged victorious in a three-way race which saw vote splitting between the Democratic Party and the newly formed centrist People Party. In the following election, Oh Gi-hyoung defeated Kim by a margin of more than seven points, winning back the seat for Democratic Party. Oh won re-election in 2024, garnering 52.83% of the vote and defeated People Power Party challenger Kim Seon-dong in a one-on-one match.
