If your machine is like the touch screens here in WI, you check the tape in the little window on the lower, right hand side of the machine. When the tape records the vote you wanted to cast, then you cast the vote.
The screen doesn’t count; the tape counts.
No, it is all electronic. Not a single paper verification. It’s all “put on a card (magnetic strip)”. One is supposed to verify it with the summary screen at the end, that is all. But how do I know if the summary is what will get recorded? And how do I personally prove it to anyone?
As a programmer I could easily show one thing on the screen and tape, and then record another value behind the scenes that gets counted. I could easily do it only on every 10th Republican vote, every 5th independent, etc.
If the "tape" on the side of the machine you're referring to has a human-readable portion that tells you your vote was recorded as "x", it could still easily record your vote as "y" behind the scenes. It's not the human-readable part that gets counted. It's the invisible electronic value that gets counted.
I don't know any computer programmer who thinks electronic voting is a good idea. Perhaps they exist, but they're probably all Democrats and Satanists.
