One of the reasons people had their signatures rejected from the Bandon Petition was because they were not registered to vote or they were not registered in the location of the petition. You have to be registered and active to be able to sign petitions.
I got three people registered during the last Petition Drive, but their signature still did not count, because the registration has to be counted the same day they signed the petition.
Link to registration
April 24 is the deadline for voter registration for the May 15 primary.
Online registration on the website of the Oregon secretary of state can be completed by 11:59 p.m. April 24. The state has the only online registration.
Registration also can be done by postcards as long as they are postmarked by April 24.
Voters must register again if they have changed their names or addresses, or want to change party affiliation.
Under Oregon law, only registered Democrats can vote to nominate Democratic candidates in the primary, and registered Republicans can vote for Republican candidates. This year, voters not affiliated with a party
can request a Republican ballot, because Republicans have opened their primary, but those voters cannot vote in the presidential contest.
All voters, regardless of affiliation, can vote in the primary on ballot measures and candidates for nonpartisan offices.
