The gun measure (Initiative Petition 43) is already dead, thanks to the Democrats in the Oregon Legislature.

The Attorney General has until May 23 to issue a "certified ballot title." Any commenter then has until June 7 to file a ballot title challenge in the Oregon Supreme Court. Supporters and others (including the Attorney General) then have until June 18 to file responses. The challenger(s) then have until June 25 to file reply memos. The Court then takes the matter under advisement and has been taking an average of 2 months to decide such cases. The deadline for submitting signatures is July 6. You do the math.

Also, if the Court finds that the certified ballot title needs to be changed at all, the matter returns to the Attorney General for another week to make the change, and then there is another week for any party to challenge the modified title and then unlimited time for the Court to rule. The Court can then find fault with the modified title and send it back to the Attorney General for more cycles of revision and challenge.

Secretary Of State Dennis Richardson has tried to adopt rules allowing petitioners to gather signatures on sheets that print the full "certified ballot title," while the Oregon Supreme Court review is underway. But Democrats in the Oregon Legislature blocked that in the February 2018 session. So the gun measure is already dead.

There is an article at http://www.eastoregonian.com/eo/capital-bureau/20180517/ballot-initiativ..., which implies that IP 43 is still alive. It is dead, thanks to the Democrats in the Oregon Legislature, as are IP 40 for net neutrality and IP 44 to require firearms to be locked while stored.
