This looks quite nice. Presumably for PR elections? I came up with something similarish when doing a mixed member system that used score/approval ballots, and you could vote for candidates and their parties together / separately.
@matija True. If individual ballot data can be used, then the funding that results from each could be split equally across the candidates approved on that ballot. But this still might not be very satisfactory.
@matija Ahh, I think I understand what you meant better now. Still, I'm not sure where the incentive for bullet voting comes from (at least in a realistic situation); approval thresholding is a more common (and more realistic) strategy for informed voters.
The governing coalition opted for true open lists. Phragmén-MMP would be better because most of us like the idea of independent candidates.
Though open lists are still better than MMP with runoff.
