Is the plan is to first arrange a Condorcet election between all
candidates and then between the top 5 candidates? In that case if the
voters have not changed opinion between the two elections (and the
voters vote sincerely) then the results of the second round should
usually be a copy of the results at the first round. In that sense
the results of the first round could be considered also final. But if
the law requires to arrange an election between 5, why not then.
Too many candidates in an election may be a problem since that makes
voting tedious. One option would be to allow large parties to have
e.g. 2 candidates each and small parties to have only one candidate.
In this case also republicans would have a say on which one of the
democrats will win (assuming that democrats will have majority). I'm
not sure if democrats want that or if they prefer to first elect the
"best democrat" among the democrats and name only that candidate in
the final election. Having several candidates in the final election
may make the probability of electing some of them higher.
My point is just that running primaries and the number of candidates
each party wants to nominate and the maximum number of candidates in
the final election do have impact on how the system works.
Condorcet should work ok in all phases (I don't expect strategic
votes to be a major problem).
