2007 South Korean Presidential Election: Lee Myung-bak's Landslide Victory
On 19 December 2007, South Korea held a pivotal presidential election that fundamentally shifted the nation's political landscape. The election resulted in a decisive victory for Lee Myung-bak of the Grand National Party, marking a significant return to conservative leadership in the Blue House—the official residence and office of the President of South Korea—for the first time in a decade.
Lee Myung-bak secured his mandate with a nearly 2-to-1 margin over his closest rivals, achieving the largest victory margin since the reintroduction of direct elections in 1987.

The Path to Nomination: Party Primaries
Before the general election, each major party held its own internal selection process, known as a primary, to determine their official nominee.
Grand National Party Primaries
The Grand National Party primary featured five candidates, including former Mayor of Seoul Lee Myung-bak and National Assemblywoman Park Geun-hye. The process utilized a weighted system: 20% from opinion polling and 80% from the popular vote of pre-registered electors. Lee Myung-bak won with a narrow margin, leading to some controversy regarding the polling method, though Park Geun-hye conceded the race.
Grand Unified Democratic New Party Primaries
The Grand Unified Democratic New Party saw a crowded field of nine candidates. After an initial opinion poll narrowed the field to the top five, a series of regional races and mobile voting determined the winner. Chung Dong-young was officially named the party's nominee at the UNDP National Convention on 15 October 2007.
Democratic Labor and Creative Korea Primaries
The Democratic Labor Party utilized both online and offline voting methods. Following a two-round process, Kwon Young-ghil emerged as the nominee. Meanwhile, Moon Kook-hyun secured the Creative Korea Party nomination through a mobile voting system with 95% support from party members.
Controversies and Investigations
The election period was not without legal and political tension. It marked the first instance in South Korean history where a president-elect faced investigation by a prosecutor. Additionally, later reports and leaked diplomatic cables raised questions regarding the handling of the BBK embezzlement scandal and investigations into Lee Myung-bak's real estate information by the National Intelligence Service.
