Hi Richard,

I am sending a P.S. to my P.S. below.
I hope the message got through despite the bad English in the first part of
my email below.
If not, please let me know, and I will try to explain further.

I wrote below:

"I think the reform of a two round system could take two different paths:
1) a three round system where a second run-off is held between the
runoff winner in the second round and the
Condorcet/Bucklin/Approval/Score winner from the first round, if the
Condorcet/Bucklin/Approval/Score winner would be different from the
two run-off candidates."

I would like elaborate this proposal a little.
Call the Condorcet/Bucklin/Approval/Score winner K.
Assume K is different from the two second round runoff candidates R1 and R2.
The third round could make use of the same ballot paper as the second round,
by making the voter first vote between R1 and R2 (the normal runoff in the
second round).

Then the voter would make two more choices:
Between R1 and K (i.e the question would be: if R1 would win the runoff with
R2 would you prefer R1 or K as president (or chairman/leader etc.)?)
Between R2 and K (i.e the question would be: if R2 would win the runoff with
R1 would you prefer R2 or K as president (or chairman/leader etc.)?)

If R1 would win the second round runoff, then the votes R1 vs K would be
counted as the third round votes.
If R2 would win the second round runoff, then the votes R2 vs K would be
counted as the third round votes.

The same informtion could be encoded in a ranked ballot with R1, R2 and K,
but this could maybe fool some voters to think that the same method was used
in the third round as the method for selecting K in the first round - this
is just a minor detail.

 The first round ballot could be either a ranked ballot, or a ballot with a
FPTP (bullet vote) ballot part on one side and a ranked ballot part on the
second side (a double-vote ballot). The double-vote ballot would enable the
voter to bullet vote for a different candidate than he would give his first
preference to on the ranked ballot part of the ballot, which might be
optimal if different voting tactics are used for both elections, or if the
voter cannot make up his mind between two of the candidates and would like
to see them both in the combined second/third round.

The first-round ballot could also be used in the two round election to
reform the FPTP system.

I would endorse this three-round system as a good way to reform runoff
elections, like the French presidential elections, which is likely to get
needed political support. The runoff winner meets the
Condorcet/Bucklin/Approval/Score winner and the voter only has to vote
twice, so it is difficult to see why a voter would not like this expansion
of the current system.

A footnote: a similar construct is found on the ballot for
constitutional referendums in Switzerland, I think.
 There is a proposal of constitutional change to be voted on, and
a "compromise" proposal from the Swiss government or Parliament too (I don't
remember which).
First the voter votes between "change the constitution" Yes/No
If the voter votes "Yes" then he has to select between the proposed change
and the proposal from the government/parliament.
Then, if "change the constitution" gets a majority, then a second round is
held between the two different proposals.

Best regards
Peter Zborník
