Did you watch the video of the guy who said those machines can be rigged to change things to whatever you want. He could engineer a perfect 50%/48% election and poll workers would never know it.
I watched another guy on Fox a couple years ago that was showing how you could even give voters a printout of their vote, but that would not be what the machine did.
I believe this is why the push for electronic no paper trail voting.
Some psephologists (scientists in the art of voting) have suggested a system whereby citizens would get receipts that they could trace back into the body of tallied votes at any reasonable time after an official tally was announced. And if it was different, they could file a complaint, presenting their receipt.
Link, please?
In related news: This afternoon on public transit I overheard a couple of men (age mid-thirties I guess) discussing the election. They couldn't figure out how Romney lost Colorado. "I mean, Boulder, Denver..." one guy said thoughtfully. "He was a nice guy, a traditional guy..." The conversation then turned to Colorado's cold and snowy high-elevation climate.
Both of these guys were black, BTW,
