It'd be really easy to write a program that made you think you were voting for someone when you were actually voting for someone else. How easy?
It took me about four hours.
That's to write the whole thing. To write the bit that skews the results only took about ten minutes.
Computers don't lie. They don't tell the truth, either. They do what they are told to do. In fact, it's actually much easier to game an electronic voting device than it is a mechanical one. For one thing, mechanical machines that cheat have to cheat through mechanical processes. Gears have to have missing teeth, or there have to be extra gears and doohickies and other bits and pieces to tamper with voting results as they come in. That alone makes mechanical tampering difficult, because those modifications are very obvious to inspectors.
