Two days of early voting for the July 30th by-elections has begun.
Those that cast ballots today and tomorrow will help determine the winners in Korea's largest ever by-elections, where 15 parliamentary seats are up for grabs.
Six of the vacant seats are in Seoul and Gyeonggi-do province, and analysts say winning the upper hand in those races may very well determine who won the greater election.
And according to the last opinion poll results released on Wednesday, the ruling Saenuri Party is in the poll position.
In Seoul's Dongjak-B constituency, considered a barometer of public sentiment in the capital, the ruling party candidate is in the lead.
However, there's a lot of road between now and next Wednesday.
Two opposition candidates bowed out of their respective races on Thursday to circle the wagons around the liberal candidate.
The field has narrowed in the Dongjak-B race, where at last check the ruling party candidate Na Kyung-won had an overwhelming lead.
Candidate Ki Dong-min of the main opposition party has dropped out and thrown his support behind the Justice Party candidate Roh Hoe-chan in hopes of boosting the opposition's chance of winning.
The Justice Party candidate in the Suwon-D constituency of Gyeonggi-do province also dropped his candidacy on Thursday, making it largely a two-horse race between the ruling party's Yim Tae-hee and the main opposition's Park Kwang-on .
