It doesn't have to be fine-grained. If we think X and Y are 
the front-runners, and we like X better than Y, we can fully 
approve X along with everyone we like better, and fully 
disapprove Y along with everyone we hate worse. We can scale 
the candidates we rate in between if we like, but since our 
(course-grained) assumption is that X and Y are the likely 
leaders we can probably make a similar course-grained 
assumption that the in-betweeners don't have large 
probability deltas associated with them, so our choices on 
those candidates are not going to be as important. We can 
use an above-the-mean-utility strategy on those candidates 
(using the mean of only the candidates we do think are 
front-runners -- which also works if we think there are more 
than two likely front-runners).
