Richard Posner: “technological fixes for the sorts of problem that emerged in Florida in the last election, the simplest fix being to replace the punchcard ballot (especially when the votes are counted at the county rather than precinct level) by the optical-scanning (Marksense) system, are likely to be opposed by incumbents. Incumbents have adapted to whatever system they were elected under and are reluctant to take their chances with a new system. This is one example of the uneasy relation between law and technology, and another is the indifference (at least until 2000) of most students of election law to the serious technological issues involved in our election methods.”
I still favour the paper ballot system, but I grant that it probably works better for a small country like Canada than it would for a country like the United States.
