Not that the decision should take place in groups first, but if it did for
informational purposes (to see whom the different states or districts
preferred), it might be embarrassing if all of the states or all of the
districts agreed on who should win, but the method (when applied to all of
the ballots at once) picked someone else.
It seems to me that a method that is inconsistent in this sense can be
thought of as having some kind of internal friction that wastes
If the district wins were borderline or a result of cyclical tie breaking,
this would be understandable. If the district wins were all decisive,
this would reflect badly on the method, in my opinion.
