Hi Peter, My quick responses to this:
--- En date de : Mer 16.6.10, Peter Zbornik <[email protected]> a écrit : >I got a second question from one of our members (actually the same guy >which asked for the first time): >If I just bullet vote in a Condorcet election, then I increase the chances >of my candidate being elected. >If I have a second or third option, the chances of my prefered candidate >to win is lowered. None of this is guaranteed. Actually listing additional preferences can also help a preferred candidate. >Q: In this case why should any voter not bullet-vote? You should not bullet vote if the possible use of voting for a second preference outweighs the likelihood that the second preference will hurt your first preference. It is not obvious that a voter should be trying to support his favorite candidate to the exclusion of everything else. He should be trying to get the best result possible on average. >My argument starts: >If I vote for a candidate who has >50% of the votes, then it does not >matter if there is a second or third choice. >If my prefered candidate A gets <50% of the votes, then it makes sense >to support a second choice candidate B. >However if the supporters of B only bullet vote, then maybe B's >supporters get an advantage over A? Yes, that can happen. But it doesn't follow from this, that everybody should bullet-vote. If A and B are similar candidates then all of these voters benefit from the A>B votes even though the B voters only voted B and denied A chance to win. Most likely if the A voters bullet-voted also, then some other candidate would win. >... at this point I realize, that I don't know enough about Condorcet >and/or Schulze to answer the question. > >Why is it not rational to bullet vote in a Condorcet election if you are >allowed not to rank some candidates? It could be rational in some cases, but it is not rational in general. In general it makes sense to express your preferences.
