Look at the 50s, the core support base for Lee Jae-myung

In the Hangil Research survey released today (October 21), negative evaluations among those in their 50s were 30.9%p higher than positive evaluations.
Evaluation Ratio
Positive: 33.9%
Negative: 64.8%
Gap: Negative leads by 30.9%p
Why did this happen?
The key is the possibility that dissatisfaction with the livelihood economy and security/diplomatic policies has accumulated.
Livelihood Economy, Security, Diplomacy: 40.6% of all respondents cited setbacks in these areas as the reason for the decline in the President's approval rating.
They probably realized it after getting hit in the head lol
Weren't the 50s the core support base? How did the score get reversed like this?
