It has been eight years since the 2000 presidential election revealed the many flaws that existed in the mechanics of U.S. voting systems. Despite that debacle, many states have not made even basic improvements to assist voters — such as providing user-friendly Web sites that tell them how to register and where to go to vote. A new study has found that many state election Web sites are too difficult for voters to find and use. Few even provide such fundamental information as whether a person is registered and what will be on the ballot.
