The MassGOP’s one-time national committeewoman will helm a push by social conservatives to put the state’s newly signed transgender rights law to a ballot question, nudging the state party — led by bill signer, Gov. Charlie Baker — into an ?awkward position.

Chanel Prunier, who lost her seat as the state’s national committeewoman this spring, has signed on as chairwoman of the ballot question committee, Keep Massachusetts Safe, which will push to repeal the law Baker signed earlier this month that bans discrimination against transgender people in public places, including restaurants, bathrooms and locker rooms.

The law’s opponents have petitioned to put a question on the 2018 ballot — when Baker will presumably be running for re-election — and are in the midst of gathering the more than 32,000 signatures they need to move forward.

They argue that the law raises privacy concerns for women and children, and Prunier, in an email, said police and business owners “will be afraid to stop” those who abuse the law by wrongly claiming to be transgender “for fear of being sued.”

Baker, after remaining noncommittal to the legislation for months, ultimately backed a version of the bill that required the attorney general’s office to issue regulations on what action should await people who assert gender identity for an “improper purpose.” Prunier, however, said she has “zero confidence in (Attorney General ?Maura Healey) to produce effective ?regulations.”

“I believe the law is a serious threat to the safety and privacy of women and children, as well as completely unnecessary given protections that were already in place and current cases taken up by MCAD,” Prunier wrote.

Prunier rose to the committee post in 2013, giving voice to the social conservative wing as it sought more control of the party, including in its successful push of a party platform two years ago that embraced traditional marriage.

Her perch atop the ballot question committee comes on the heels of her narrow loss for her committee post to state Rep. Keiko Orrall, who Baker publicly backed. It also came amid Baker’s own monthslong push to reshape the party through its state committee elections by supporting a slate of candidates — a move ?rankled party conservatives called unprecedented by a sitting ?governor.

It leaves the party staring down a clumsy position: Watching one of its leading conservative voices pushing to reverse a law its party leader backed, all while he is ?expected to try to hold the Corner Office for the party.

Asked Friday, the state party didn’t address where it stands on the law or the potential for its ?reversal.

“The MassGOP is supportive of the ballot initiative process as a way for the people of the Commonwealth to make their voices heard,” MassGOP spokesman Terry MacCormack said in a statement.

Kasey Suffredini, co-chairman of Freedom Massachusetts, said the law — subject to years of debate on Beacon Hill — ultimately emerged, thanks in part to the backing of businesses and ?Republicans themselves.

“The folks who are trying to put this on the ballot are just out of step with the majority of voters in Massachusetts,” Suffredini said, “including Republican voters, including Republican lawmakers and the governor himself.”
