Moon Jae-in has done it again.
He grabbed victory in the main opposition Democratic United Party's 11th regional primary on Wednesday.
The race was held in Daegu and surrounding North Gyeongsang Province, a traditional conservative stronghold.
Moon received 57 percent of the vote, while Kim Doo-kwan came in second with 20 percent and Sohn Hak-kyu in third with 18 percent.
So now, with only two more rounds to go, Moon is positioning himself to be his party's nominee.
He leads the race with nearly 51 percent of total accumulated votes.
Sohn is at a distant second with 23 percent.
If Moon maintains a level above 50 percent of total votes through the end of the race, there will be no run-off, meaning Moon will be the opposition camp's presidential nominee.
The DUP will hold its last two primaries in Seoul and Gyeonggi Province this coming weekend.
And once the party wraps up its month-long primary, potential presidential candidate Ahn Cheol-soo is expected to announce whether he will run for president.
The Joongang Daily reported Wednesday that Professor Kim Meen-geon met with Ahn a couple of days ago.
And Kim said that Ahn's pool of supporters known to the public now, is only a fraction of his support base, and that there are many more associates and powerful figures who will throw their support behind Ahn, if he decides to run.
Ahn is known to have met with former Finance Minister Lee Heon-jae, Cho Yong-kyung, Vice Chairman of Posco Engineering, and a number of college professors from different fields.
The liberal opposition is expected to unite with a single presidential candidate to go against the ruling party's Park Geun-hye in the December election.
But experts say, it still remains to be seen what the DUP's presidential nominee would do if Ahn announces his candidacy.
