PA Voting Machine gave Obama vote to Romney

My wife and I went to the voting booths this morning before work. There were 4 older ladies running the show and 3 voting booths that are similar to a science fair project in how they fold up.

I initially selected Obama but Romney was highlighted. I assumed it was being picky so I deselected Romney and tried Obama again, this time more carefully, and still got Romney. 

I asked the voters on either side of me if they had any problems and they reported they did not. I then called over a volunteer to have a look at it. She him hawed for a bit then calmly said “It’s nothing to worry about, everything will be OK.” and went back to what she was doing. I then recorded this video.

The Pennsylvania Machine was  quickly taken offline recalibrated with a test run, and put back online. ''We've had no complaints since then," Mathew Keeler, a spokesman for the Pennsylvania Department of State, told Mother Jones.
