Voters in Arizona and Nebraska will face competing ballot measures. What happens if they both pass?

Voters in Nebraska and Arizona will see competing measures on their November ballots — in one case about abortion, in the other about primary elections. If voters approve them all, what happens next could be up to the courts to decide.

Like more than a dozen other states, Arizona and Nebraska have constitutions stating that if two or more conflicting ballot measures are approved at the same election, the measure receiving the most affirmative votes prevails.

That sounds simple. But it’s actually a bit more complicated.

That’s because the Arizona and Nebraska constitutions apply the most-votes rule to the specifically conflicting provisions within each measure — opening the door to legal challenges in which a court must decide which provisions conflict and whether some parts of each measure can take effect.
