She also served as the unofficial first lady of South Korea after her mother Yuk Young-soo was killed by a North Korean sympathiser from Japan.Seat of mentorMoon, whose father is a refugee from North Korea, is seeking to occupy the seat of his mentor, the liberal President Roh Moo-hyun."It is going to be a negative election campaign,” said Kim Jun-seok, a political science professor at Dongguk University in Seoul."People will split between the ‘pro-growth’ generation that supports Park Chung-hee and the ‘pro-distribution’ generation that supports Roh Moo-hyun.”The polls suggested a tight race between Park and Moon after another candidate Ahn Cheol-Soo, a left-leaning software mogul with no party affiliation, left the campaign in a bid to consolidate liberal votes.A poll conducted on November 24 by JoongAng Ilbo newspaper showed Park with 44.7 per cent support, slightly ahead of Moon’s 41.3 per cent. If elected Park will become South Korea’s first female president.The survey was held after Ahn - who enjoyed huge popularity among young and some previously undecided voters - announced his departure Friday and threw his support behind Moon from the liberal opposition Democratic United Party.
