Theory Briefing
- Rep. Kwak Sang-eon, son-in-law of late President Roh Moo-hyun, voted against his party's criminal bill despite strong family-legacy ties to the progressive bloc.

- The family connection to Roh Moo-hyun adds a loyalty dimension that makes the defection more striking than a typical cross-party vote.
