One way to look at the amendment problem on a given subject is to regard every combination of consistent amendments as a separate issue (equal to separate candidates in a candidate election). To limit the number of amendments to some reasonable number some minimum percentage of the legislators would have to show a desire for an issue (such as 30 percent) (equivalent to a nominating petition for candidates). How many issues can get a yes majority approval ? The Condorcet method would then do the head to head pairings of all of such majority approved issues. If one issue beats each other, then it should be adopted. If there is not a single beats-all winner with 3 or more majority approved issues (as may be likely), then I suggest that the majority approved issue with the lowest number of first choices should lose. The head to head math would be redone. Repeat the cycle until there is a single winner.
