I think that for most people we could get what amounts to a meaningful answer to that question by asking them to respond to an enquiry like this, which focuses on the binary choice posed in an election:
"Now you have seen the performance of this person in the office to which they were elected, how would you answer these questions:
(A) If you voted for this candidate, do you now think it would have been better if you had voted for the candidate of the opposing party who presented themselves at that election?
(B) If the answer to (A) was 'No", and knowing what you now do about the person's performance in office, do you think that you might now have voted for the opposition had their candidate been different from the one who actually presented themselves?
(C) Assuming it to be possible, do you think it would be better if the person in office were to leave that office and hand over to the designated successor, either voluntarily or involuntarily?"
