> * Most of the lower choices are not informed choices. When we discuss races with 3 or 4 candidates, we're talking about 3 or 4 contenders. Contenders are by definition known to many people. I presume that in just about any method, the little-known obscure candidates will have no chance of winning (except maybe Borda).
To take two specific methods, why would anybody give an approval vote to a candidate from an obscure party like Natural Law or whatever? How would that lower choice hurt the favorite? In Condorcet, that obscure candidate would probably lose all pairwise contests (except against other obscure candidates). How exactly will John Hagelin undermine George Bush and Al Gore with Approval or Condorcet? And if you don't know who John Hagelin is, obviously that lower choice is not a threat. > * Lower choices are used to harm earlier choices by helping some other > candidate. Let's look at 3-level approval. If somebody has a majority of "preferred" votes he wins. Similar to IRV. If not, nobody is eliminated, but additional votes are distributed to candidates based on how many people rated them "acceptable." Admittedly, a vote is being given to your second choice, even though your favorite is still in the running. However, other people can now give votes to your favorite. Nobody is eliminated. Favorite still has a chance. Would you rather see favorite eliminated when your vote is given to somebody else, or would you rather see him still have a chance? Which case is better is not clear-cut. Some people dislike the idea that a lower choice is benefiting while favorite remains in the game. Others like the idea that favorite still has a chance. Since there's no clear philosophical advantage, we have to look at strategic questions, among them monotonicity, IIA, etc. > * The lower choices are not netural.

Many people that I talk to seem convinced that any candidate from a different party must be bad. They are convinced that all Republicans want to take food from children, or all Democrats want to rob them blind. Will their minds suddenly open if they have an IRV ballot in front of them?
