I read the ballot. The word "adding" there is pretty clear.
A “yes” vote supported adding a right to own and bear firearms to the Iowa Constitution and require strict scrutiny for any alleged violations of the right brought before a court.
Could have been better worded, to be sure.
It should have been "adding a right to own and bear arms amendment".
Here is the actual amendment:
Right to keep and bear arms. Sec. 1A. The right of the people to keep and bear arms shall not be infringed. The sovereign state of Iowa affirms and recognizes this right to be a fundamental individual right. Any and all restrictions of this right shall be subject to strict scrutiny.
Notice, it doesn't even mention firearms.
It is all about saying the right shall not be infringed, not adding a right, and that the state of Iowa affirms and recognizes the right, it does not create the right.
I forget if it is the Secretary of State who wrote the description, or someone else.
