Republican Party's Shift on Abortion Sparks Internal Battle The post-Roe era has seen a significant shift within the Republican Party, as anti-abortion activists find themselves sidelined. Despite the disavowal of Project 2025, a conservative plan for abortion bans, by Donald Trump and a promise in the new G.O.P. platform to advance access to in vitro fertilization, a powerful conservative Christian battalion has continued its fight to restrict not just abortion but also I.V.F. These activists are quietly laying the groundwork to end abortion from conception, using an incremental strategy to influence regulatory language, state party platforms, and the definition of when life begins. R. Albert Mohler Jr., president of the Southern Baptist Theological Seminary, has been mobilizing evangelicals against I.V.F. and sees their challenge as spanning generations. The Southern Baptist Convention, the country's largest Protestant denomination, recently opposed the use of I.V.F. for the first time, redirecting the abortion conversation within evangelical churches and providing a new data point for Republican politicians. Additionally, several state Republican parties have added new anti-abortion language to their platforms, despite the national party's differing direction. The movement to advance "fetal personhood" through the 14th Amendment is also gaining momentum, with groups like Students for Life of America seeking increased regulation of I.V.F. and working to incorporate fetal personhood into forthcoming abortion-related legislation. A new anti-abortion "minority report," emphasizing discontent with the party platform, has been issued by a coalition of Republican delegates. The coalition's efforts have found support in figures like JD Vance, the vice-presidential candidate, who has defended Trump's backtracked positions on abortion using anti-abortion rhetoric. The American Association of Pro-Life OB-GYNs, which sued the F.D.A. to restrict the distribution of mifepristone, is also preparing for future advocacy campaigns despite a recent Supreme Court rejection. The article also discusses other efforts to regulate I.V.F., such as a report being planned by the American Association of Pro-Life OB-GYNs to identify ethics-related gaps in I.V.F. and suggest "guardrails." Meanwhile, Kristen Ullman, president of the Eagle Forum, believes the anti-abortion movement can progress in regulating I.V.F. despite the disappointment of the G.O.P.'s position. Despite the Republican Party's recent lack of specificity regarding abortion-related policy priorities, the anti-abortion coalition remains determined and recognizes the potential for their ambitions to be advanced in another Trump term. They see opportunities to use officials in federal agencies to chip away at access to abortion and fertility treatments through new regulations. Overall, the article outlines the Republican Party's evolving stance on abortion and the determined efforts of anti-abortion activists to advance their agenda despite internal and external challenges.
