Ballot measures may be an option elsewhere, too. Hildy Saizow, president of Arizonans for Gun Safety, said an initiative is one of the things the group will be considering as it reconsiders strategies. An organizer in Oregon was focused on the Legislature for now but wouldn't rule out a ballot measure in the future if lawmakers fail to pass a proposed bill there.
