Conservative Christianity's alignment with the Republican Party at the end of the 20th century is one of the most consequential political developments, both for American religion and American party politics. In the proceeding four decades, what has been the nature of this relationship? The inclusion-moderation thesis suggests that once religious movements are integrated into political parties, their interests are often co-opted by broader party interests and their positions moderate. For the Christian right in the U.S. there is mixed evidence for the inclusion-moderation process. Considering all the evidence, the most apt description is that conservative Christianity has transformed the Republican Party, and the Republican Party has transformed conservative Christianity. With its inclusion in the Republican Party, the Christian right has moderated on some aspects. The movement has become more professional, more attuned to the more widely accepted, secular styles of democratic politics, and more engaged in the broader goals and positions of the party. Conservative Christianity has also failed to fully achieve some of its most important goals and has lost some of its distinctiveness. In these ways, the party has changed the Christian right. At the same time, the Christian right has altered Republican politics. National candidates have changed their positions on important social issues, including abortion, gay rights, and religious freedom. The party's platforms and judicially strategies have been strongly affected by movement's interests, and conservative Christian activists have come to be central to the Republican Party. It's stability and strength within the party have given the movement power. In these areas, the Christian right has evangelized the Republican Party rather than moderated. A fair assessment is that for the Christian right there has been partial but quite incomplete adherence to the inclusion-moderation process.
