I thought the Rebuilding Korea Party's role was over....

Right now, the Rebuilding Korea Party is showing the Democratic Party the right path to take.
Is this the beginning of a three-party era?
I personally think this is very desirable.
The expansion of the progressive spectrum is progressing strongly.
What happens when a single party grows too large—
this feels like a major historical trend significant enough to be in textbooks.
The things many people challenged in the past,
like Rhyu Si-min and Roh Hoe-chan—will it finally be realized this time?
