Meh, not necessarily. High turnout can often mean people are unhappy with their government on some serious fundamental level, etc.
IMO, a better way to rate it is how "free" people are to vote, rather than what % votes. Not voting can be a choice, after all. Isn't that freedom?
Also, the US isn't sitting next to Iran or something, their right there at the top, how is this supposed to be an insult?
Also, it seems that anti-abortion stances of a country actually might hurt it's measure, as it's addressed on the website of the group that made this list, under where they talk about individual countries. While I'm pro-choice, I find that odd.
