Voting Fraud in Florida?

Just in case you hear about the study done by a prof at Berkeley, and aren't sure what to make of it: the study referred to by some folks in the media has been effectively countered by Craig Newmark, who includes a few demographic variables that have changed over the past four years.

Let's hear it for good theoretical modeling and the clear use of statistical estimation.

Why are people so quick to assume fraud in electronic balloting but not in all our billions of day-to-day electronic business transactions? Bill Sjostrom has a good explanation of the differences in trust, to which I linked earlier

Hint to Craig Newmark's results: the demographic changes did not involve a movement of evangelical Christians to Florida.
