You could say "Rank all candidates you approve of" or even "List the
candidates you like in order of preference. Ignore all other
candidates." Such a ballot would be easier for the average voter to
understand and fill out. If there are fifteen people running for office,
and you like three, hate three, and don't know anything about the
remaining nine, you can just say the equivalent of A>B>C, and ignore the
rest. No dummy candidate would be necessary Sure, it wouldn't give as
much information as a ballot that has all of the candidates ranked, but
it would make certain forms of strategic voting (such as burying) more
tedious and less attractive.
Then just use the ballots to find the Condorcet winner. Such a ballot
could be used with Approval-Completed Condorcet or Ranked Approval
Voting, or any other completion method that takes into account Approval
votes. For example, you could say "If there is a cycle, compare the two
candidates with the lowest Approval score in the cycle, and drop the
pairwise loser. Continue until there is a single winner." Or whatever.
