Is Lee Jae-myung entering a lame-duck period?

The clear evidence of Lee Jae-myung's lame-duck period is
the fact that Choo Mi-ae, who should just focus on being a good Gyeonggi Governor,
brought up the personnel issues of this cabinet reshuffle
and spat in Lee Jae-myung's face.
Choo Mi-ae has always been someone who doesn't care about anything,
but when Lee Jae-myung's approval ratings were high,
she refrained from picking fights and causing trouble.
However, after seeing this cabinet reshuffle that looks like a total mess,
she immediately resorted to personal insults lol.
If this isn't a lame-duck period, then what is?
