All ballots in Oregon are paper -- there are no voting machines at all since vote-by-mail started a few years ago. No Diebold salesmen need call on our Secretary of State.
All registered voters are mailed a ballot before the election and either return it by mail or drop it at a collection point by election day. Voters must sign the outside of the envelope and the signature is compared with the one from the voter registration card. The ballot is placed in a security envelope so the voter's selections remain anomymous.
The best part is that you can take as long as you like to consider your choices from the comfort of your easy chair.
Amazingly even with this convenience and simplicity, the voter turnout is still low.
