Well, at least once you have finished evaluating what you think may happen
(with whatever probabilities) it becomes straight-forward, as you simply
approve everyone who is better than your expectation (the average of
outcomes' utilities weighted by their odds of occurring).

I guess under Approval it is frequently of consequence to the vote you
decide on, what you think other voters will do. But I don't think the
nature of the considerations is particularly unique. Condorcet still has
the "one party with two candidates" defection issue.
