The magic number 55% determines the outcome of an election...What is the turnout rate in past elections? = Korea

In South Korea, there is a lot of interest in whether the magic number of 55% voter turnout, which determines victory or defeat, will be applied in this election as well. Considering the trends in general elections over the past 20 years, voter turnout is over 55%.
If it was higher, it would have been advantageous for the Democratic Party (opposition), and if it was lower, it would have been advantageous for the People's Power (ruling party) affiliate. Since 2000, the average voter turnout from the 16th to 21st elections was 57.1%. The results of the general election are serious.
If the voter turnout decreased from the 55% threshold, the people's power line would have had the upper hand. In the 18th general election in 2008, the turnout was 46.1%, but the Grand National Party won 153 seats (51.
17%), and the United Democratic Party held 81 seats (27.09%), resulting in a crushing defeat for the Democratic Party. The general election was held after the inauguration of the Lee Myung-bak government, and the Democratic Party fell behind in the presidential election.
It was the worst election in history, with a difference of 5.7 million votes. On the other hand, the 21st general election in 2020 had the highest voter turnout (66.2%) since the 14th general election held in 1992.
In both general elections, the Democratic Party won overwhelming victories. Including satellite parties, it held 180 seats (60%). On the other hand, the Future United Party and its satellite party Future Korea Party won 103 seats (34.33%).
The party suffered a crushing defeat, barely managing to defend its line of blocking constitutional amendments. The closer the vote was to the magic number of 55%, the closer the election was. In the 20th general election in 2016, when the voter turnout was 58%.
Although the Democratic Party became the largest party in both elections with 123 seats (41%) and the Saenuri Party with 122 seats (40.67%), the difference was only one seat.
In the 16th general election in 2000, which recorded a voter turnout of 57.6%, the Grand National Party won 133 seats (48.71%), and the New Millennium Democratic Party and the Liberal Democratic Union won 132 seats.
It was a very thin race with only one seat difference between the two candidates, who held 48.35% of the seats. In the 19th general election in 2012, the Saenuri Party won 152 seats (50.66%) and the Democratic United Party won 127 seats (42.3%).
3%), and the Saenuri Party won with a difference of 25 seats. Voter turnout was 54.2%. In the 17th general election held in 2004, the turnout was 60%, and the Uri Party won 152 seats (5
0.83%), the Grand National Party held 121 seats (40.46%), and the Open Uri Party won with a difference of 31 seats. Who will lead the casting board of people in their 20s and 30s to the voting booth?
The Democratic Party candidates are sending out messages encouraging people to vote ahead of the general election.
On the 29th, Lee Jae-myung, the leader of the Democratic Party of Korea, posted on his YouTube channel
"I'm worried because there are reports that the opposition party supporters are a little less willing to vote. My vote is important, but I want other people, those who support me, not to give up and to reach out to their acquaintances," he said in a live channel.
"I think that in the end, making sure people vote will be the key to the election."
