Thanks @miniature-tiger! In this case, it was indeed very clear. However, not all are that clear. Having the blockchain data helps a lot, though. Pattern recognition is an interesting approach, and also ML as mentioned in @lovenfreedom's comment. I tried once to analyze only a few days in the context of "who votes mostly together with whom" in a brute-force approach - This gave a few interesting results, but the processing time requirements would not have scaled to larger time ranges. Applying ML/AI techniques could indeed help there to build models...
