In November 2024, Iowa voters will decide on a constitutional amendment that would prohibit non-citizens from casting ballots in state and local races and also permit 17-year-olds who will be 18 by the general election to vote in primary elections.
To put a legislatively referred constitutional amendment before voters, a simple majority vote is required in both the Iowa State Senate and the Iowa House of Representatives during two successive legislative sessions with an election for state legislators in between.
The constitutional amendment was introduced as Senate Joint Resolution 9 on Feb. 10, 2021. It was passed unanimously in both chambers during the 2021-2022 legislative session. The measure was also passed unanimously by the state legislature during the 2023-2024 legislative session and was certified for the ballot on April 5, 2023.
All state constitutions mention U.S. citizenship when discussing who can vote in that state’s elections. In 43 states, constitutional language discussing citizenship says who can vote (e.g. “every citizen” or “all citizens”), but does not state that noncitizens cannot vote. In seven states (Alabama, Arizona, Colorado, Florida, Louisiana, North Dakota, and Ohio), constitutions provide that citizens, but not noncitizens, have the right to vote.
