It seems like they intend to end Jung Chung-rae's political career..

If they run for Seoul Mayor and lose, their political career is over lol
Kang Kum-sil
Han Myeong-sook
Park Young-sun
Song Young-gil
And.. what was that guy's name? Lee Jae-myung's pick.. the one who was a district head..
Anyway, there's a long line of people whose political careers were cut short by losing to Oh Se-hoon after running for Seoul Mayor.
