I have figured out why "New Lee Jae-myung" and the core supporters are splitting...

New Lee Jae-myung supporters support Lee Jae-myung.
The core supporters support the Democratic Party's Lee Jae-myung.
That is the difference.
Because New Lee Jae-myung supporters support only Lee Jae-myung, they attack Democratic Party supporters who offer criticism to Lee Jae-myung as "2-jjik" (supporters of the opposition).
The existing core supporters of the Democratic Party support Lee Jae-myung, but not simply because of him, but because he was the Democratic Party's Lee Jae-myung..
They no longer consider an Lee Jae-myung who shakes the very foundations of the Democratic Party as an ally..
They didn't vote for him to be a president for everyone.
That's just a nice way of putting it; he's a president for everyone..
They didn't vote for him to be someone in the middle, indecisive and lukewarm..
They thought Lee Jae-myung would know how to wield the sword properly..
The existing Democratic Party "scholars" were frustrating... so they expected Lee Jae-myung to wield the sword decisively..
Since Lee Jae-myung's election, nothing has been properly reformed... if anything, the Blue House is the biggest obstacle to reform..
There is not a single country in the world where a structural majority exists on its own..
In every country, two or three major forces compete for power to maintain balance, and the force that produces the president carries out its own policies..
That is democracy..
Black and white fought, and white won..
But then the representative of the white side suddenly says, "I am neither black nor white, I will practice 'gray' politics..."
Damn it, it's only natural that he's treated like a lunatic who gets cursed out by both the black and white sides..
