Intercepted in popmedia: Some dude of Shoup Corp which makes voting machines, or used to 21 years ago (there are no parts available), demonstrated that you can lock out choices after you've pulled one lever. Which would eliminate certain bozos double-punching their political-hollerith cards. What a concept. These days we call it a radio-button. [Actually a variant, "one-shot" kinda radio button in this case, because you can't rollback your vote. That's probably a deficiency, but it might be due to this barbarian mechanical tech making illegit rollbacks possible if you allow voter rollbacks.] I suppose various floridians would like a modal message box asking, You're voting for BROWNE (LIB), is this correct? [YES] [VOTE AGAIN] Much like crypto, its User interface, user interface, user interface...
