Why is the Democratic Party unnecessarily boosting Han Dong-hoon's stature? lol

Han Dong-hoon is just an independent lawmaker who was even shunned by the People Power Party.
If Lee Jae-myung had succeeded, Han would have been completely ousted from the political scene without even being able to set foot in it.
So why is the party making it possible for Han Dong-hoon to dominate during Kim Seung-won's appointment?
They should have verified the message before attacking the messenger,
but the Democratic Party kept focusing only on attacking the messenger.
Where did Han Dong-hoon even get that information? lol
"We will expel you"
The conclusion is Kim Seung-won's voluntary resignation, followed by a war of revelations.
It only ended up instilling the perception that Han Dong-hoon is actually trustworthy.
Regardless of whether Han Dong-hoon is talking nonsense or not,
the Democratic Party should have seriously reviewed whether there were issues with Kim Seung-won.
Why are they acting like such amateurs?
They shouldn't just let Han Dong-hoon becoming the No. 1 trusted politician slide like this lol
