Five days before the re-election in April, three terrestrial broadcasters including SBS conducted a joint poll.



First, in the case of the Seoul Mayor's by-election, if candidate Oh Se-hoon, the power of the people, was a single candidate for pan-optics, we asked who to vote.



Democratic Party Park Young-sun 30.4%, people's strength Oh Se-hoon 47.0%.




When candidate Ahn Cheol-soo became the single candidate, Park Young-sun 29.9% and Ahn Cheol-soo 45.9%.




Candidate Se-Hoon Oh and Chul-Soo Ahn are both superior to Candidate Park Young-seon outside the margin of error.



Se-Hoon Oh and Chul-Soo Ahn decided to reflect'fitness' and'competitiveness' in half each in the unified public opinion poll. It was not possible to cover the superiority and inferiority.




When asked which of the 13 candidates to vote for the mayor of Seoul without the unification condition, Park Young-sun 27.3%, Oh Se-hoon 30.2% and Ahn Cheol-soo 24.0%.



All but the three candidates were less than 1%.



Next, we asked who to vote among the candidates running for the Busan mayoral by-election.



Democratic Party candidate Kim Young-chun was 26.7%, people's strength Park Hyeong-jun candidate 38.5%.



All other candidates were around 1%.



For questions about the issues that will have the greatest impact on the Busan mayoral elections, 24.8% of measures to revitalize the local economy, 20.0% of real estate policies, 13.9% of the construction of Gadeokdo New Airport, 13.4% of allegations of land speculation by LH employees, and prevention of corona 19 vaccines The response was 9.6%, followed by L City sales suspicion 6.7%.
