DES MOINES, Iowa — Two amendments to Iowa’s Constitution have passed following Tuesday’s election.

Iowa voters decided to approve an amendment that essentially codifies the state’s constitution to match federal law, allowing 18-year-olds to vote. They’ve been able to since 1971 because of federal law, but Iowa’s constitution still has outdated language with the age of 21. The new amendment also includes language specifically addressing citizenship and making it clear that if the citizen turns 18 by the time of the general election they are also eligible to vote in the primary election.

The second amendment approved on the ballot addressed some vague language in the constitution about what happens in the transfer of power should a governor pass away, resign, or suffer a permanent disability that causes a vacancy.

Voters approved the following text:

Section 17 of Article IV of the Constitution of the State of Iowa is repealed and the following adopted in lieu thereof:

Sec. 17. Lieutenant governor or lieutenant governor-elect to become or act as governor or governor-elect. If there is a temporary disability of the governor, the lieutenant governor shall act as governor until the disability is removed, or the governor dies, resigns, or is removed from office. In case of the death, resignation, or removal from office of the governor, the lieutenant governor shall become governor for the remainder of the term, which shall create a vacancy in the office of lieutenant governor. This section shall also apply, as appropriate, to the governor-elect and the lieutenant governor-elect.
