Be sure to check out this helpful comparison chart of single winner election methods.
The page describes several election methods, describes several desirable properties of election methods and indicates whether each method passes or fails the method.
If readers wonder why I oppose instant runoff voting but like approval voting this page is a good start.

Kathy Dopp (1) has written a scathing criticism of instant runoff voting (aka IRV 2).
It’s a list of many criticisms but it is rooted in Dopp’s election integrity and election auditing background. IRV is a disaster from an election integrity point of view – primarily because it is not ‘summable in precincts’.
I agree with much of what she has to say. However, I find her paper to be somewhat difficult to read since the latest version frequently switches tone and voice between her voice and that of Abd ul-Rahman Lomax (who posts profusely on the election methods’ email list and the range voting message board.) [Update: 6/17/08 – see correction in comments] .
Here is Dopp’s summary:
Instant runoff voting (IRV) is a method for counting “ranked choice” ballots where each voter ranks the candidates – first choice, second choice, etc. The IRV counting process proceeds in “rounds” where the candidate with the fewest votes is eliminated in each round and that candidate’s votes are reassigned to the remaining candidates using voters’ choices. IRV sounds enticing to voters who can express their preferences, but according to the new report, IRV does not solve the problems it is promoted as solving and causes significant new problems.
…
According to Kathy Dopp, the report’s author, “Instant runoff voting is a threat to the fairness, accuracy, timeliness, and economy of U.S. elections. The U.S. needs to solve its existing voting system problems and then carefully consider the options before adopting new voting methods.”The full report “Realities Mar Instant Runoff Voting – 17 Flaws and 3 Benefits” is found on-line at

One main point I disagree with her about:
The National Election Data Archive recommends restoring verifiable integrity to elections first before implementing alternative voting methods.
There are many problems and issues with our election system.
They include integrity, election methods, gerrymandering, representation via districts vs other options, the electoral college, voting on Tuesdays rather then more accessible times.
In my view, getting rid of lousy election methods is pretty important.
(aside: a very loosy-goosy attempt to compare the importance of various reforms (+ discussion))

An article featuring Range Voting is in the news. William Poundstone is interviewed by Mother Jones. This is also featured on Slashdot.
The basis for the coverage is Poundstone’s new book Gaming the Vote: Why Elections Aren’t Fair (and What We Can Do About It)
From the MotherJones interview:
It’s heartening to know, as primary season begins, that ours may be the worst of all the voting systems in common use. That’s the takeaway from Gaming the Vote: Why Elections Aren’t Fair (and What We Can Do About It), the latest of eleven books by William Poundstone, a professional skeptic who studied physics at the Massachusetts Institute of Technology before he began pumping out nonfiction in 1982.
…
Poundstone became interested in voting theory after reading about Arrow’s Impossibility Theorem, a 59-year-old paradox wherein economist Kenneth Arrow, now a professor emeritus at Stanford University, identified what he perceived as a fundamental flaw in our democracy: Put simply, he argued that devising a perfectly fair voting system is mathematically impossible.
…
Mother Jones: Is there a way around Arrow’s Impossibility Theorem?William Poundstone: For decades, there was almost a kind of despair among voting theorists of getting any better system than we had. What’s interesting, though, is that the impossibility theorem doesn’t apply to systems where you score the candidates rather than rank them. With scoring, you’re essentially filling out a report card—if you think there are two candidates who deserve four stars you can give them both four stars—whereas with ranking you have to artificially give one a number one and one a number two. That turns out to be crucial.
MJ: And yet plurality voting—where a person can vote for only one candidate for a particular office—is the most common system in use. What’s wrong with it?
WP: Whenever you have two candidates whose support overlaps, that’s bad for both of those candidates, the obvious example being Nader and Gore in 2000. So a candidate can be a spoiler and cause the second most popular candidate to win. This is something that’s been appreciated at least going back to the 18th century, and people have tried to devise different ways of dealing with it, but for a very long time this was one of those unsolvable problems.
