you approve anyone who you approve of

approval voting is a special case of score voting where the range of scores is limited to 0 and 1. if you want to express different levels of preference, you can expand this range and get full score voting. the downside is this puts a heavier burden on the voter to decide on scores (if it's 0-99, i give my first choice 99, but what do i give my second choice? 98? 75? 50? my choice might depend on what i expect other voters to think makes sense as a score)
