Oregon also lets a party remain ballot-qualified party if it polls 1% for any statewide race at either of the last two elections (although such parties must have registration of at least one-tenth of 1%).
The part of SB 1527 that eases the definition of a party was amended into the bill just a few days before the legislature adjourned.
