Goldmund]The touchscreen needs re-calibration.... if they were to touch the name under Obama, then Obama would have been checked. It's not changing the vote - it's registering the touch in the wrong spot on the screen. But hey, anything that looks like someone is trying to cheat is news.
Actually, this machine didn't have a calibration issue. It was just straight up defective and had to be pulled. Every button worked normal except for Obama, if it was a calibration issue then every button would be the equal distance off. It's explained in the comments section directly under the video.
. 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.
