The trends and narratives of recent U.S. electoral campaigns have shown how candidates appeal to religious constituencies, from evangelical and Catholic voters, for support based on shared values. Rhetoric related to religious liberty has been particularly effective, especially in issues like abortion and same-sex marriage. This paper analyses the strategic use of religious rhetoric in the recent U.S. electoral politics. How have recent U.S. presidential campaigns strategically employed religious rhetoric to mobilize specific voter demographics? What are the legal implications of invoking religious liberty in contemporary U.S. electoral politics, particularly about the First Amendment's Clauses? The paper examines the complex interplay of law, religion, and politics in shaping the trajectory of U.S. elections.
