Like I said, I would love score voting (range voting). Its my preference for precisely the reason you state: it provides the expressiveness to show partial support. And it does so without the constraints of IRV or ranked voting. To my mind, score is the "superset" voting model. However, approval is something that could be installed with relatively low cost and low effort. And it is nearly immediately understood by anyone. Score voting requires a tiny bit more education (although it too is easy to understand; and I suspect most voters would get the hang of it after a couple elections). I would be disappointed with IRV/ranked because it seems the most difficult to understand, requires rework of ballots, and disallows equal scoring (thereby reducing expressiveness). It would be a shame to squander voting reform momentum to end up with IRV.
