The metropolitan cities of Seoul and Incheon, along with Gyeonggi-do province are shaking out to be the fiercest battlegrounds in this local election.
Senior member of the ruling Saenuri Party plan to join the campaign trail next week to throw their weight behind their mayoral hopefuls in Seoul and Incheon.
They need all the help they can get.
Ruling party candidate for Seoul mayor, Chung Mong-joon, who is trailing by 15 points in the polls behind incumbent Park Won-soon, handed out food to elderly citizens at a welfare center, while Park had lunch with college students.
Over in the western port city of Incheon, the ruling party's mayoral candidate Yoo Jeong-bok is also behind in the polls by more than 10 percentage points.
He and his challenger in the race, incumbent Song Young-gil, visited elderly community centers.
And in Gyeonggi-do province, where the race for governor is much tighter, the main opposition candidate Kim Jin-pyo of the New Politics Alliance for Democracy was joined on the campaign trail by co-chairman of the party, Ahn Cheol-soo.
The ruling party's Nam Kyung-il, who's in a neck-and-neck race with Kim, shook hands with the elderly at a welfare center in the city of Seongnam.
Ahn Cheol-soo's presence in Gyeonggi was for a reason, as a win by the NPAD there would constitute a major win, as the province has a greater population than Seoul.
The main opposition alliance is trying to appeal to undecided voters who may be disappointed by the government's poor handling of April's ferry disaster.
