Elected President

Moon Jae-in
Democratic

Early presidential elections were held in South Korea on 9 May 2017 following the impeachment and removal of Park Geun-hye. [1] The elections were conducted in a single round, on a first-past-the-post basis, and had originally been scheduled for 20 December 2017. However, they were brought forward after the decision of the Constitutional Court on 10 March 2017 to uphold the National Assembly's impeachment of Park. Following procedures set out in the Constitution of South Korea, Prime Minister Hwang Kyo-ahn succeeded Park as the acting president. After Park was removed from office by the Constitutional Court's ruling, acting president Hwang announced he would not run for a term in his own right. [2] [3] [4]

Contents

Opinion polling before April consistently placed the Democratic Party's candidate, Moon Jae-in, runner-up in the 2012 election, as the front-runner. Second place in the opinion polls was initially held by former UN Secretary-General Ban Ki-moon, who declined to run in February, followed by Ahn Hee-jung, whilst he lost the Democratic primaries to Moon. Support for People Party founder Ahn Cheol-soo then surged, threatening Moon's lead in the polls throughout early April, before descending to approximately equal that of Liberty Korea Party's candidate, Hong Jun-pyo, in final polls.

Moon won the election with 41 percent of the vote, defeating his nearest opponent, Hong, by a nearly 2-to-1 margin. Under the Constitution of South Korea, if a president dies, resigns, or is removed by impeachment, a new election must take place within 60 days. As a result, unlike previous presidential elections, president-elect Moon took office immediately upon the confirmation of the result by the National Election Commission, with the inauguration at the National Assembly on the same day.

Background

Park Geun-hye of the conservative Saenuri Party (renamed just prior to the election in February 2017 as the Liberty Korea Party) won the previous presidential election in 2012, succeeding Lee Myung-bak of the same party.

The Saenuri Party lost the parliamentary election in April 2016, with opposition parties including liberal Democratic Party and People Party winning a majority in the National Assembly. Commentators described the result as leaving Park a lame duck president, as South Korean presidents are barred from reelection. [5] [6] [7] and the Nikkei Asian Review noted that, in the wake of her "crushing defeat", "rivals sense a prime opportunity to complete the power shift in the December 2017 presidential vote". [5] The Korea Times stated: "The drama of deals and power struggles for next year's election has already begun." [8]

Impeachment of President Park Geun-hye

On 9 December 2016, President Park was impeached by the National Assembly by a vote of 234 for and 56 against (with seven invalid votes and two abstentions) after her implication in the 2016 South Korean political scandal. The Constitutional Court reviewed the motion of impeachment. Per the Constitution, Park's powers were suspended until the Constitutional Court could review the case, and Prime Minister Hwang Kyo-ahn became acting president.

The Constitutional Court had 180 days to decide whether to uphold the impeachment. On 10 March 2017, Park was formally removed from office, with a unanimous ruling by all eight of the Constitutional Court's justices supporting her impeachment. A presidential election would have to be held within 60 days. In the interim, Prime Minister Hwang served out the remainder of the 18th term until election day.[ citation needed ]

The presidential election had previously been scheduled for 20 December, with Park barred from running due to the constitutional ban on any sort of presidential reelection. However, with Park's removal from office, the elections were brought forward to 9 May in order to ensure that a new president would be able to take office within 60 days of Park's removal, as required by the Constitution.

Opinion polling

Opinion polls throughout 2017 showed Moon Jae-in as the leading candidate. Polls prior to the conclusion of the Democratic primary (which included his rivals to the nomination) had Moon at around 30% support, and polls conducted after he had won the primary showed generally consistent results of around 40% by April.

Polling showed a significant decline in support for Ahn Cheol-soo during April. While at the beginning of the month he was polling close to Moon, and even exceeded him in a few polls, by May his support had dropped to around 20%. This decline coincided with rising support for Hong Jun-pyo. By the time of the polling blackout period began on 3 May, Ahn and Hong were recording similar levels of support.

<span class="mw-page-title-main">Impeachment of Park Geun-hye</span> 2016 South Korean president impeachment

On 9 December 2016, Park Geun-hye, the president of South Korea, was impeached as the culmination of a political scandal involving interventions to the presidency from her aide, Choi Soon-sil. 234 members of the 300-member National Assembly voted to impeach and temporarily suspend Park's presidential powers and duties. This exceeded the required two-thirds threshold in the National Assembly and, although the vote was by secret ballot, the results indicated that more than half of the 128 lawmakers in Park's party Saenuri had supported her impeachment. Thus, Hwang Kyo-ahn, then Prime Minister of South Korea, became acting president while the Constitutional Court of Korea was due to determine whether to accept the impeachment. The court upheld the impeachment in a unanimous 8–0 decision on 10 March 2017, removing Park from office. The regularly scheduled presidential election was advanced to 9 May 2017, and Moon Jae-in, former leader of the Democratic Party, was elected as Park's permanent successor.
