(Barack Obama, Mitt Romney, Joe Biden, Paul Ryan)
Youtube user Centralpavote uploaded this video of an electronic voting machine checking the box for Mitt Romney when he tries to vote for Barack Obama. He wrote in the video's description:
"Being a software developer, I immediately went into troubleshoot mode. I first thought the calibration was off and tried selecting Jill Stein to actually highlight Obama. Nope. Jill Stein was selected just fine. Next I deselected her and started at the top of Romney's name and started tapping very closely together to find the 'active areas'. From the top of Romney's button down to the bottom of the black checkbox beside Obama's name was all active for Romney. From the bottom of that same checkbox to the bottom of the Obama button (basically a small white sliver) is what let me choose Obama. Stein's button was fine. All other buttons worked fine."
The machine has been taken off line.
