- Finding 1: GL-PvdA were 2.8-10.5% of avg inter-party distance apart pre-merger
- Finding 2: Merged party started most cohesive (#1 in 2023) but now 55% above avg spread
- Finding 3: Converged to 4.5% by Q3 2023, essentially indistinguishable
- Finding 4: GL/PvdA were most stable parties (10-25% drift) while VVD/D66 moved 70-177%
