The Center for Election Science doesn't hide their preference* and advocacy:
> Let’s put approval voting ON THE MAP!
* Generally, each organization has some kind of bias, and I appreciate it when they are up-front about it.
My preferred group would have these biases / goals:
1. Valuing a diverse group of people
2. Valuing clear and honest discussion about member preferences in voting systems
3. Valuing understanding among the group members
4. Help group members form alliances with each other, should they desire to organize and do advocacy, because while each of us might have our 'preferred' voting system, we all benefit from moving beyond the 'worst' voting systems
