The revelation on Wednesday evening that Melania Trump’s forthcoming memoir includes a full-throated defense of abortion rights, an issue her husband Donald Trump has repeatedly flip-flopped on during his presidential campaign, left people on both sides of the issue less than impressed.

“Restricting a woman’s right to choose whether to terminate an unwanted pregnancy is the same as denying her control over her own body,” Melania Trump wrote in her memoir. “I have carried this belief with me throughout my entire adult life.”

Melania Trump also defended the right to abortion later on in pregnancy – a procedure that her husband has repeatedly demonized. (Less than 1% of abortions occur at or past 21 weeks of gestation.)

“Sadly for the women across America, Mrs. Trump’s husband firmly disagrees with her and is the reason that more than one in three American women live under a Trump abortion ban that threatens their health, their freedom and their lives,” Harris campaign spokesperson Sarafina Chitika said in an email. “Donald Trump has made it abundantly clear: If he wins in November, he will ban abortion nationwide, punish women and restrict women’s access to reproductive health care.”

Melania Trump’s remarks also took anti-abortion activists by surprise.

“It’s hard to follow the logic of putting out the former First Lady’s book right before the election undercutting President Trump’s message to pro-life voters,” Kristan Hawkins, president of the powerful Students for Life of America, posted on Twitter/X on Wednesday night. “What a waste of momentum.”

Over the last several weeks, anti-abortion activists have grown increasingly fed up with the former president, who has struggled, alongside the rest of the Republican party, to redefine his messaging on abortion rights amid outrage over the overturning of Roe v Wade.

Earlier in his campaign, Trump bragged about appointing three of the US supreme court justices who voted to overturn Roe, branded himself the “most pro-life president ever”. After Kamala Harris became the presidential nominee, however, Trump has pledged that his administration “will be great for women and their reproductive rights” as well as vowed not to sign a national abortion ban – just weeks after refusing to say that he would veto one.

Melania Trump’s comments may feel like a further insult to the anti-abortion voters who feel abandoned by Trump, said Republican campaign strategist Liz Mair, adding anti-abortion advocates run potent get-out-the-vote operations. Those advocates were key to Trump’s 2016 victory.

“This might be just another thing that piles on to make pro-lifers think: ‘I just can’t with this guy.’ A lot of them were single-issue voters anyway,” Mair said. “He’s not really giving them much of an incentive to show up and do anything to his benefit.”

When Tresa Undem, a pollster who has surveyed people about abortion for more than two decades, heard the comments, she immediately thought: “Wow”. Then she thought: “It’s a campaign move.”

However, Undem is not sure who, exactly, the move is for – especially given the Trumps’ sometimes frosty relationship in public. Melania Trump has rarely aired her political views and has largely vanished from Donald Trump’s 2024 campaign.

The odds of Melania Trump’s comments comforting moderate or conservative voters who support abortion rights are “fairly slim”, Undem said.

“These strong feelings – they did not suddenly appear this year, right? So she clearly has had no influence on him when it comes to policy related to abortion,” Undem said. “I don’t think she’s ever been positioned, or voters ever think of her, as having any kind of policy position or weight or influence on Trump.”
