Thirty-four state senators have joined 54 members of the Iowa House in voting for a resolution that ultimately could add a gun rights amendment to the Iowa Constitution. The same proposal must pass the legislature again in 2019 or 2020 before it could be presented to voters who decide whether amendments are added to the state constitution.

Senator Matt McCoy, a Democrat from Des Moines, says backers of the proposal are “completely tone deaf” to public opinion.

McCoy was among 15 senators who voted no. Critics argued the proposal’s call for courts to use “strict scrutiny” when reviewing gun laws would lead to upending reasonable gun regulations.
