[EM] Conditional YES/Head to Head legal language

[DEMOREP1 at aol.com]

1. The following shall be used for the election of 1 person to an executive 
or judicial office.

2. Each voter may vote YES or NO on each choice and rank each choice using 
number votes (1, 2, etc.).

3. A majority shall be a majority of the number of voters voting on any 
choice.

4.  (a) If no choice receives a YES majority, then the legislative body 
corresponding to the office shall fill the vacancy (but none of the ballot 
choices shall be chosen). (b) If a choice does not get a YES majority, then 
it shall lose. (c) The number vote rankings of other choices shall move up on 
the ballots having such losing choice.

5. If only 1 choice receives a YES majority or if 2 or more choices receive a 
YES majority and 1 of them receives a first rank number votes majority, then 
he/she shall be elected.

6. If no choice receives a first rank number votes majority, then additional 
rank number votes shall be added one rank at a time to see if 1 or more 
choices get a majority.

7. If 1 choice gets a majority, then he/she shall be elected.

8. If 2 or more choices receive a majority, then all combinations of 2 
choices shall be made using the number votes (and transferring the first 
choice votes from other remaining choices, if any, to the lowest ranked 
choice on the ballots involved).

9. (a) If a choice has less first rank number votes and transferred votes 
than each other choice, then it shall lose.  (b) The number vote rankings of 
other choices shall move up on the ballots having such losing choice and this 
step shall be repeated.

10. If a choice has more first rank number votes and transferred votes than 
each other choice, then he/she shall be elected.

11. If neither happens, then the choice with the highest margin of loss in 
any combination shall lose and, if necessary, the 2 prior steps shall be 
repeated with the remaining choices.  Example- B 250, C 190, margin 60 is the 
highest among all the combinations so that C loses.

12. If a tie happens, then a lottery shall be used.
