History
Since its establishment, Gangbuk A has more often elected members of centre-left, liberal parties to represent the constituency. Kim Won-gil of the centrist-liberal National Congress for New Politics was the first member to represent the constituency. Kim won re-election in 2000 as a member of the centre-left Millennium Democratic Party, but joined the conservative Grand National Party ahead of the 2002 South Korean presidential election. Kim ran as the Grand National Party's nominee for Gangbuk A in the 2004 election, but was defeated by Oh Yeong-sik of the liberal Uri Party by more than ten points. In the following election, Oh was defeated by Cheong Yang-seog of the Grand National Party. However, in the 2012 election, Oh won back the seat in a rematch against Cheong. Cheong won back the seat in 2016 as a member of the conservative Saenuri Party, securing 39.52% of the vote and narrowly beating out Democratic challenger Cheon Jun-ho. Cheong lost to Cheon Jun-ho in the following election, who won in a landslide with 57.75% of the vote. Cheon won re-election in 2024 in a one-on-one battle against Jun Sang-bum of the conservative People Power Party.
