The June 13 by-elections are to fill the 12 lawmaker positions vacated after former lawmakers quit to run for the local elections or were stripped of their seats due to illegalities.
The poll showed the Democratic Party of Korea (DPK) was dominant in 11 out of 12 electoral districts, while the rival conservative Liberty Korea Party (LKP) was defeated everywhere. The ruling party failed to take the first place only in Gimcheon, North Gyeongsang Province, where it did not nominate a candidate. There, an independent candidate gained 29.1 percent, ahead of 22.8 percent of an LKP candidate.
The outcome would deal a serious blow to the LKP, because it is likely to lose in districts that have long been considered as home turf of the conservatives. The poll shows the conservative bloc is still failing to appeal to the public following the massive corruption scandal involving former President Park Geun-hye who belonged to the predecessor of the LKP.
