--range is of course not immune to spoiled ballots, but it seems to do better than rank-order ballots (IRV, specifically) and (and this part is surprising) plurality voting, at reducing spoilage. But range is not better than approval voting at reducing spoilage & voter errors. See http://www.rangevoting.org/SPRates.html although this page could use some updating (it refers to various new data, which you can examine via hyperlink, but ought to be updated to incorporate that data directly; if you edit this page's plaintext source to do that & email result to me that'll happen) -- Warren D.
