It's easier to rig an electronic voting machine than a Las Vegas slot machine, says University of Pennsylvania visiting professor Steve Freeman. That's because Vegas slots are better monitored and regulated than America's voting machines, Freeman writes in a book out in July that argues, among other things, that President Bush may owe his 2004 win to an unfair vote count. We'll wait to read his book before making a judgment about that. But Freeman has assembled comparisons that suggest Americans protect their vices more than they guard their rights, according to data he presented at an October meeting of the American Statistical Association in Philadelphia.
