Hand Marked Paper Ballots are the only type of voting machines which are secure and safe, and should be the National Standard.
The Dominion machines also allow Machine-Marked Paper Ballots, which are NOT the same thing.
These take an input from the touchscreen, process the input in the computerin an opaque fashion, then print your vote on a paper "ballot". Your printed paper ballot shows your INPUT, but there is no way to audit and be sure your intent transfers to the vote totals which get reported to the Registrar.
This type of machine apparently was abused in 2016 in Ohio, Georgia, Illinois, Michigan Wisconsin etc by altering software/firmware, which resulted in final votes not aligning with anticipated results.
To add insult to injury, in most of these states, they are now planning to equip these machines with cellular modems, so they may communicate wirelessly with other machines, ostensibly at the Secretary of State offices in those states(?), but who is controlling this?
This is a HUGE vulnerability in our voting systems.
Many Registrars are adopting these systems because they are so "user friendly"; not a good enough reason to compromise our voting systems and chains of custody.
Contact our Registrar of voters to demand they have public information meetings to explain and demonstrate how they will insure elections integrity despite the vulnerabilities of the machines.
Jennifer Cohn is doing fantastic research on problems with these Machine-Marked Voting Machines:
