if it's misaligned, then you're going to get the kind of problems that have been reported. >> eric: so let me ask you this is this a software glitch, or is it something more insidious? could it be deliberate? >> no. it's probably a glitch. each machine has to be carefully tested and calibrated to make sure it's been aligned properly. if it gets out of alignment, then you'll have this kind of problem cropping up. i assume that they just haven't been properly calibrated or tested by local election officials. >> eric: just a coincidence that the reports have been votes for romney going to the obama column? >> well, look, there is no way to really know. but what this does say is look, every one of these machines at the end, puts up a summary screen of all the choices made by the voters. they have to very carefully look at that and make sure that the machine has exactly recorded what they've done before they hit that final button that casts the vote.
