So, I guess there's going to some fierce campaigning over the next few days
Will there be any variables that can turn the tables?

Well, this time around, what political pundits have said is that there is a distinctive feature in that people are just giving their support towards the government's drive for peace.
As it's the first nationwide election since President Moon Jae-in took office -- it would have been seen as a means to assess the government's failures and successes.
We initially thought the MeToo movement, the government's unpopular economic policies,... such as real estate policies,... and an amendment to minimum wage bill,... as well as an online opinion rigging scandal all could have been factors that could have hurt the government.
Another variable was the possibility of a merger between candidates,... but now that early voting has started,... that's not an option.
Experts say new possible allegations regarding candidates, voter turnout,... as well as undecided voters now hold the key.
Polls showed that between 20 and 40 percent of people answered that they are undecided or don't know who to select.
There's also a bloc of voters known as shy conservatives -- who don't tell pollsters that they support the main opposition Liberty Korea Party.
