My personal belief, digital or electronic polling should cease entirely. It's too easy to manipulate, just as the examples and descriptions in this topic.
If they say that it takes too long to count the votes manually by hand, remember, there is almost a 3 month period between the swearing in after election.
If that still isn't enough time, push the date back as necessary. This isn't brain surgery.
Paper ballots on the other hand, can't appear and disappear into thin air from whence it came. At least not without damn good explanation and proof. They're physical, they can be checked for authenticity, and I am 100% in support of having voter id cards.
I don't know of a single place in the USA that does not require that an ID card be issued, even if there is no drivers license. If such a place exists (maybe sanctuary cities) they should not be allowed to exist.
And if there is such a place, void/discredit every vote that comes from that place until they can verify with 100% certainty that the votes are true and correct.
No ID, no vote. It's really that simple. Federal government wastes more money on studying the sex habits of snails than it would to issue any CITIZEN without a drivers license an ID card that has a valid social security number.
No voter id, no vote. Mandantory for everyone, they can't say minorities are being suppressed if it's required of everyone, and that solution would pass constitutional muster.
