Everything becomes clear if you look closely at Min-seok's wording.

When Jae-myung's approval ratings drop... Min-seok's wording will start to change...
Up until now, he has been saying things like "We will consult with the ruling/government"...
Watch how much it shifts to "The party will make demands," "We will convey the public sentiment," or "The government must revise it"...
It looks like an anti-Ban (anti-Lee Jae-myung) Min-seok will appear soon..
