“We don’t believe those rights should be subjected to majority vote.”

Conservatives are testing new tactics to keep abortion off the ballot following a series of high-profile defeats.

In Arizona, Florida, Nevada and other states, several anti-abortion groups are buying TV and digital ads, knocking on doors and holding events to persuade people against signing petitions to put the issue before voters in November.

Republicans are also appealing to state courts to keep referendums off the ballot, while GOP lawmakers in states including Missouri and Oklahoma are pushing to raise the threshold for an amendment to pass or to make it to the ballot in the first place.

The emerging strategy aims to prevent abortion rights groups from notching their third, and largest, set of ballot measure victories since Roe v. Wade was overturned. And while conservatives celebrated the fall of Roe for returning the question of abortion rights to the people, these efforts are seen as an implicit admission that anti-abortion groups don’t believe they can win at the ballot box — even in red states — and that the best way to keep restrictions on the procedure is to keep voters from weighing in directly.
