They did not
They got Roe repealed. It took 50 years but they did it. Don’t think they’re any more ok with marriage equality:
Nearly eight years after the Supreme Court legalized same-sex marriage and several months after Congress codified gay nuptials, Iowa lawmakers proposed banning such unions in their state constitution.
“In accordance with the laws of nature and nature’s God, the state of Iowa recognizes the definition of marriage to be the solemnized union between one human biological male and one human biological female,” the joint resolution, introduced Tuesday by eight Republican members of the Iowa House of Representatives, states.
If the measure becomes law, it would conflict with the Supreme Court’s 2015 landmark decision to legalize same-sex marriage nationwide, Obergefell v. Hodges, coupled with Congress’ bipartisan passage of the Respect for Marriage Act late last year. Therefore, it is unclear that such a law could be enforceable, as federal law and the federal Constitution take precedence over state law.
Iowa Rep. Brad Sherman, one of the bill’s eight co-sponsors, said in an email that the joint resolution “would take several years to accomplish.”
“Should the people of Iowa vote for such an amendment, laws would have to be adjusted to make laws fair for all,” Sherman said.
They are playing the long game. Don’t rest on your laurels.
