On April 30, the Oregon House Rules Committee introduced HB 3521, which would provide that any citizen for whom the state has data will automatically be registered. Persons put on the voting rolls would then be notified, giving the individual a chance to choose a party or independent status, and also giving the person a chance to decline to become a registered voter. Here is the text of the bill.
The automatic registration idea is used in Great Britain and other foreign countries, but as far as is known, has never been used in the United States. Thanks to Blair Bobier for the news of the bill. The bill had a hearing on May 8; see this story.
