Unlike Joe Biden, Kamala Harris will be a genuine champion for abortion rights | Moira Donegan

When he was still the nominee, Joe Biden’s preferred euphemism for abortion was “Roe”. He would talk about “upholding” Roe v Wade even after June 2022, when the US supreme court struck it down. Reproductive rights advocates bristled at this, pointing out how many people had been denied abortions under Roe, and how flimsy the decision’s protection of reproductive rights had been on personal-autonomy or sex-equality grounds.

Frankly, it was hard to get the president to talk about abortion at all. He seemed to avoid even the word “abortion”. When he did talk about the procedure – and the bans on it that Republicans have unleashed across the country – he preferred to focus on women who had been denied emergency abortions for wanted pregnancies in the midst of tragic health complications.

Abortion, in his hands, became an issue in which sad, troubled and helpless women could be aided by the mercy of heroic men like himself – or like that of the imagined doctor he referenced in his disastrous June debate with Donald Trump, a man, Biden said, who would determine whether an abortion seeker “needed help or not”. Abortion, in his telling, was an unpleasant but necessary evil that men mediated for women. It was decidedly not a matter of adult women’s rights, dignity or right of autonomy over their own bodies and lives.

Kamala Harris, Biden’s successor at the top of the Democratic ticket following his withdrawal last Sunday, has taken a different approach. The Biden administration had largely delegated abortion rights messaging to the vice-president, out of deference both for Biden’s obvious personal discomfort with the issue and his growing inability to campaign effectively at all. (The anti-choice group Susan B Anthony Pro-Life America named Harris as Biden’s “abortion czar”, a name that perhaps sounds a little cooler than they intended.) She made a multistate tour focusing on the issue earlier this year, which included what is believed to be the first public visit to an abortion clinic by a president or vice-president: a stop at a Planned Parenthood in St Paul, Minnesota, where Harris appeared with the clinic’s medical director, and commended the clinic’s staff for their “true leadership”.

“It is only right and fair that people have access to the healthcare they need,” she said .

The result was a divergence of abortion messaging within the White House, with Harris making a much more robust case for abortion, and for reproductive justice more broadly, in much more affirmative and unapologetic terms. The preferred catchphrase that she repeated when speaking about the issue was not Biden’s tepid and euphemistic “restore Roe”. Instead, Harris has made apparent reference to Dr George Tiller, an abortion doctor who was murdered by anti-choice extremists in 2009, who summarized his own approach to abortion in two words: “Trust women.”

Before Biden dropped out of the race, November’s presidential election was set to be little more than a referendum on his age. But now that he has stepped aside, Harris has an opportunity to make a much stronger case for a Democratic policy vision. And reproductive rights, an issue that has motivated women voters in large numbers even in deep-conservative states since the Dobbs decision, appears to be at the center of her agenda.

The move is good politics. Abortion rights are extraordinarily popular, and have only become more so in the years since Dobbs, mobilizing voters who would stay home or vote for Republicans when other issues are more salient. A new poll from the Associated Press finds that six in 10 Americans support abortion for any reason; other polls show even higher levels of support for abortion, especially early in pregnancy.

It’s not just that abortion, in the abstract, is popular: abortion bans, in particular, are profoundly unpopular. The reality of post-Dobbs bans has dramatically moved public opinion on the issue: since May 2019, the percent of Americans who say that abortion should be legal under all circumstances has increased by 10 points, to 35%. The percent who say it should be illegal under all circumstances – the position advocated by the Republican party platform, which supports recognition of fetuses and embryos as persons under the 14th amendment – has fallen dramatically during that same period, to just 12%.

These shifts in public opinion have had a marked impact at the ballot box. Democrats’ better-than-expected showing in the November 2022 midterms is credited to outrage against the Dobbs decision that June. But a desire to protect or restore abortion rights has driven large turnout even in heavily Republican states: Kansas , Kentucky and Ohio have all voted overwhelmingly in favor of abortion rights since Dobbs. Harris has seized on this shift in a way that Biden has not been able to, speaking passionately – and credibly – about abortion as a matter of not only health, but also dignity.

Harris has also cannily and repeatedly drawn connections between Trump’s last term, in which three anti-choice zealots were appointed to the US supreme court, and the suffering that abortion bans have caused in Republican-controlled states. She refers to the state laws prohibiting the procedure as “ Trump abortion bans ”. This focus could bear fruit in November: alongside Harris’s presidential bid, a total of five states – Nevada, Colorado, South Dakota, Maryland and Florida – will have abortion-rights measures on the ballot.

The Republican ticket, meanwhile, has leaned further and further into an ideology of misogyny and gender reaction. Trump’s vice-presidential pick, JD Vance, is a passionate and lurid misogynist; he recently referred to Harris and other Democratic women as “childless cat ladies who are miserable at their own lives”, and that childless women “have no direct stake” in America’s future. He has also suggested that citizens without children should have their votes diluted .

Childless women seem to be a particularly irksome demographic for the Trump camp’s army of prurient creeps: both the media personality Laura Loomer and the lawyer and thinktank gadfly Will Chamberlain quickly joined Vance in attacking Harris for not having biological children. It’s a fitting line of attack; after all, the very reason why Republicans are pursuing abortion bans in the first place is because they have an extremely narrow view of what women should be, one they want to enforce with the law.

Abortion-rights advocates will certainly seek to push Harris for even more commitments for reproductive freedom and justice. But Harris, at least, is willing to argue that women can be things other than mothers. Like maybe the president.
