Trader consensus heavily favors the Democratic Party of Korea (DP) at 89% to secure the most seats in the seven National Assembly by-elections on June 3, 2026, coinciding with nationwide local elections, due to strong district-level polling leads in former strongholds like Incheon Gyeyang-gu (50%+), Jeonbuk Gunsan-Gimje-Buan-gap (54%), and Gyeonggi Ansan-gap. All vacated seats were previously held by DP lawmakers resigning for local races, presidential duties under Lee Jae-myung, or legal issues, bolstering the ruling party's incumbency edge amid national polls showing DP support at 46-51% versus People Power Party (PPP) at 18-31%. Recent internal DP nomination resolutions in contested districts like Ansan-gap and Yeonsu-gap, alongside PPP leadership turmoil including its nomination committee's mass resignation, have solidified DP's positioning, though high-profile challengers like Reform Party leader Cho Kuk could narrow gaps in competitive races.
