"Through sources in our book and in this paper, we demonstrate that the abortion issue was entangled in a struggle over political party alignment before the Supreme Court decided Roe. As repeal of abortion laws became an issue that Catholics opposed and feminists supported, strategists for the Republican Party began to employ arguments about abortion in the campaign for the 1972 presidential election. We show how, in the several years before Roe, strategists for the Republican Party encouraged President Nixon to begin attacking abortion as a way (1) to attract Catholic voters from their historic alignment with the Democratic Party and (2) to attract social conservatives, by tarring George McGovern, Nixon’s opponent in the 1972 presidential election, as a radical for his associations with youth movements, including feminists seeking ratification of the Equal Rights Amendment (ERA) and “abortion on demand.”16 In reconstructing this episode, we show how strategists for the national political parties had interests in the abortion issue that diverged from single-issue movement actors, and we document some of the bridging narratives that party strategists used to connect the abortion conflict to other controversies."
