What is everyone's opinion on parallel voting?

[Damocles]

The trouble with mixed-member majoritarian systems is that they’re a clunky compromise between party list proportional systems, and single-member district systems. They attempt to both introduce better proportionality into existing single-member district systems, or to force a consensus to emerge in fragmented proportional systems, but end up sucking at both.

In the first case, parties which win a significant fraction of the vote still win a much smaller percentage of seats, which suppresses parties that enjoy broad popular support. In the second case, it compromises the legitimacy of an otherwise proportional result, which can introduce the appearance of impropriety into the election.

Furthermore, having two separate electoral mechanisms for different parts of the same legislative body is a rather clunky and inefficient system. I am also critical of the implementation of Germany’s MMP system, for this exact reason. It can create confusion and resentment towards the system from any number of corners.
