When punching the button for Romney and randomly getting Obama it is meant to happen.
I have 40 years in Aerospace Computer Experience, There is no such thing as a “Computer Glitch”, I repeat there is no such thing as a “Computer Glitch”. They are Planned Technical Difficulties. Newscasters do not know how to explain them, so they are called “Glitches”
If an event i.e. (If Romney-vote goto Obama-vote or If Obama-vote goto Obama-vote) if this is programed it will happen, other wise it does not happen. So the Obama people or surrogates want this to happen.
These can be programmed to happen every time or randomly, as they appear to be happening currently.

OTOH, there can be unintentional inputs. A dangling cuff or bracelet, steadying one’s hand on the heel, etc.
I went through utter heck trying to diagnose, over the phone no less, my mom’s random opening of windows and moving of icons.
Turned out she’d crush the mouse when moving it from one place to another. In her mind this was getting a firm grip, the computer thought of it as deliberate clicks.
But as you say, what’s happening with the voting machines is no accident.
