I cannot find by searching at the moment, but during the 2020 elections, states using Dominion and Smartmatic, the two most used voting “systems” used in the US, listed. Oregon, iirc, uses Smartmatic to tablulate ballots. I will find more info later and post.
Oregon has rotten elections, no doubt about it.
I meant machines like the old days, where you went in a booth and punched a card or selected on screen choices.
