Public school board elections have become cultural battlegrounds as groups with opposing views on education, politics, religion, and social and cultural issues vie to shape public education, their communities, and the nation. To date, little research has examined White Christian nationalism as a political force shaping these elections. This paper analyzes the November 2023 State College Area School District (SCASD) school board election in a polarized Pennsylvania town, focusing on the five "United for SCASD" candidates. Using public data (e.g., Facebook, websites, radio interviews, emails from candidates to board and administrators), the paper examines how these candidates' rhetoric -- largely drawing on Civil Rights-era minoritarian framing -- mobilized key White Christian nationalist tropes such as persecution and voicelessness. The findings explore how candidates characterized desirable versus undesirable types of unity and diversity. For instance, they advocated for focusing on students' "common humanity" and teaching American exceptionalism as unifying strategies, argued for "parents' rights" to opt children out of objectionable material, and asserted the need for "viewpoint diversity" on the board. However, they opposed the board's alleged ideological uniformity and "divisive" initiatives and curricula focusing on systemic inequities, especially concerning race/racism and gender. The data show some evidence of White Christian nationalist tropes, particularly beliefs in American exceptionalism, the trope of persecution and voicelessness, the assertion of a common cultural template for US public schools, and us-them binaries, in this case, between liberal board members and their constituents versus the U4SCASD slate and more "conservative," often rural, families.
