I don't see these as reason to be optimistic because in practical terms,
Range and Approval are neither independent of irrelevant alternatives
(candidates' presence in the election will affect strategy) nor
strategy-free (for obvious reasons).

People that interpret Arrow to simply mean "no voting method is fair"
probably don't really understand it.
