      That's right. "You" should have found some way to vote for X

      Because IRV has a traditional and (for many) intuitive algorithm,

      that (for voters who'll ignore the competitive/viable candidates)
      so as to wash away<br>
      an otherwise likely majority-defeat disqualification so would
      opposed forces have an interest in doing the opposite.<br>
      <br>
      In fact you could have post-election recriminations reminiscent of
      those that were aimed at Nader and those who voted for him
      supposedly allowing Bush to<br>

      Just the knowledge that a failure of Mono-add-Plump  is

                                & MDDTR doesn't invalidate that.<br>
                                <br>
                              </div>
                              My point, in asking about when you make
                              someone lose by raising hir from last
                              place to 1st place, was just that IRV is
                              popular and widely used. It's been used in
                              Australia for a long time, and it's used
                              in a fair number of cities in this
                              country.  ...and now has been adopted by
                              the state of Maine.<br>
                              <br>
                            </div>
                            ...in spite of its Mono-Raise failure.<br>
                            <br>
                          </div>
                          If the more embarrassing Mono-Raise failure
                          doesn't give IRV any acceptance or enactment
                          problem, then why should the less embarrassing
                          Mono-Add-Plump failure of MDDTR give MDDTR an
                          acceptance or enactment problem?<br>
                          <br>
                        </div>
                        <div>There of course have been objections to
                          IRV, some valid, some not. But I haven't heard
                          any of the IRV critics in the various cities
                          complain about its nonmonotonicity. They
                          object to implementation complexity. They
                          invalidly claim voting complexity. They
                          invalidly complain because supposedly voting
                          is supposed to be by Plurality. They repealed
                          IRV in Burlington because of the elimination
                          of a CWv.   But none of the complaints that
                          I've heard, in cities using it or considering
                          IRV, have been about its nonmonotonicity.<br>
                          <br>
                        </div>
                        <div>Why I say that Mono-Raise failure is more
                          embarrassing:<br>
                          <br>
                        </div>
                        With MDDTR, if your plump for X makes X lose,
                        it's because you added a ballot. It has nothing
                        whatsoever to do with the fact that you voted
                        favorably to X.<br>
                        <br>
                      </div>
                      With IRV, if raising X from bottom to top makes X
                      lose, then X lost for no other reason than because
                      you helped hir more.<br>
                      <br>
                    </div>
                    There are 2 kinds of nonmonotonicity:<br>
                    <br>
                  </div>
                  Did you make X lose _in spite of_ voting favorably for
                  hir?<br>
                  <br>
                </div>
                or<br>
                <br>
              </div>
              Did you make X lose _because_ you voted hir more
              favorably?<br>
              <br>
            </div>
            Of those 2 kinds of nonmonotonicity the 2nd one is more of
            an embarrassment to the method. There, the method is more
            directly acting oppositely to your action.<br>
            <br>
          </div>
          Maybe it could be said that the 2nd kind of nonmonotonicity is
          twice as embarrassing to the voting-system.<br>
          <br>
        </div>
        <div>Anyway, if IRV is so widely used and successful, then why
          would nonmonotonicity be a problem for MDDTR?<br>
          <br>
        </div>
        <div>I now feel that IRV's (mitigated) problem isn't an
          unusually high price for CD, isn't more than the "going rate"
          for CD. IRV & its derivatives are at the top of my ranking
          of method-merit for electorates who want &/or need
          ranking.<br>

                        <div>But buriers or truncators could raise that
                          approval cutoff too. Someone could bury X
                          under Z without having to approve Z. That
