“Wonder Woman” has roped herself with the lasso of truth.

Lynda Carter, star of the iconic 1970s CBS show, has backed two Democrats in an Arizona legislative race — snubbing her only sister, a Republican candidate and former Donald Trump campaign employee.

“As a native Arizonan, I am proud to endorse @KelliButlerAZ and @KarenGreshamAZ for the two LD4 seats in Arizona’s State House,” Carter, 73, posted on X Sept. 14.

“Kelli and Karen are both strong, experienced candidates, born and raised in Arizona. They are working mothers fighting for the rights that matter most to Arizonans, especially every child’s right to a quality education.”

The Carter sisters’ most obvious point of public disagreement has been over abortion — a fraught issue in the Grand Canyon State, which earlier this month repealed a Civil War-era prohibition on nearly all abortions that had been in place since the overturn of Roe v. Wade in June 2022.

Lynda Carter, who was Miss World USA 1972, is also backing Democratic presidential and vice presidential candidates Kamala Harris and Tim Walz. She endorsed Joe Biden in 2020 and former Secretary of State Hillary Clinton in 2016.

Pamela Carter served as state director for the 2020 Trump campaign in Arizona and is running to represent the state’s Fourth Legislative District as a Republican.

Arizona has 30 legislative districts, each of which elects two state representatives and a state senator.

A gym owner and former host of her own physical fitness TV program, “Get in Shape with Pamela Carter,” the GOP candidate has touted her small-business acumen and Arizona roots in her campaign.

“A reformer, small business owner, and lifelong Arizonan, Pamela has the skills and passions needed to fix what is broken in our state government and provide our state with excellent jobs, schools, and quality of life,” her campaign website reads.

Pamela Carter has also received endorsements from real estate trade groups in the state, as well as from Latinos United For Conservative Action.

Butler is a former three-term state lawmaker and currently sits on the Maricopa Community College District Board.

Gresham serves as the president of the Madison Elementary School Board.

Matt Gress, a Republican who currently serves the 4th District in the Arizona state House, is also running for re-election.

Republicans currently control both chambers of the Arizona legislature — but only by narrow, two-seat majorities.

Reps for Pamela Carter’s campaign did not immediately respond to a request for comment.
