Who or what group authored the ballot item about abortion on the Kansas ballot?

The best I could find was this info from today’s NY Times. It definitely indicates that the anti-abortion side wrote the initiative:

“The anti-abortion side used confusing language in the amendment, which suggested a yes vote would ban taxpayer funding of abortions — a ban that already exists — or allow for laws protecting victims of rape and incest, who already have legal access to abortion. They insisted they had no designs on passing a total ban on abortion, but The Kansas Reflector obtained audio from a meeting in which a state senator and amendment advocate promised to attempt to pass just such a ban. On top of that, the day before the election, Kansas voters received deceptive texts to vote yes to preserve “choice,” confusing untold numbers of voters.”

The “Value Them Both Amendment” was proposed in 2020, but failed to receive the required two-thirds majority in the Kansas House to be added to statewide ballots. In 2021, the Legislature secured supermajorities to get it on the ballot.

Kansans for Life, a pro-life organization, developed the Election Integrity and Voting Rights Project to build grassroots momentum for the amendment. Rep. Blake Carpenter, a Republican from Derby, was named director of KFL’s election project.

The proposition came out of efforts in the Kansas State legislature.
