The problem affects people who switched parties just before the registration deadline.

County elections officials had already sent voter rolls to the printers, so those ballots will go out in the mail with the voters' previous party.

Later, voters will get the ballot from the correct party.

According to the Oregon Secretary of State's Office, it's alright if voters fill out both ballots since the state database will catch the mistake.
