An essential guide to how the interactions between social norms, party politics, and expressions of prejudice are driving contemporary politics.

Antiminority rhetoric in American politics has grown more overt. What were once fringe comments on Stormfront have now become typical campaign appeals from many mainstream politicians. If there was ever a doubt, this is a poignant reminder that the boundaries of what is “acceptable” and “unacceptable” to say and do are fluid and socially enforced.

In Parties and Prejudice, Maneesh Arora offers a broad framework for understanding this new political terrain. Arora argues that the interaction between social norms and party politics determines what the political consequence of prejudicial speech will be. He illuminates this nuanced relationship by showing that norms vary based on the targeted minority group and the intended audience.

Drawing on experiments, survey data, news coverage, and real-world examples, Parties and Prejudice examines the distinctive ways that egalitarian/inegalitarian norms have developed—within each party—for Black, Muslim, and LGBTQ+ Americans. It is essential reading for understanding Donald Trump’s rise to power, the modern conservative agenda (including opposition to critical race theory and transgender rights), and threats to the development of a multiracial democracy.

A myth-busting investigation of small donors: who they are, how they spend their money, and whose campaigns actually benefit from their donations.

Many political reformers argue that more robust small donor participation in US campaigns would reduce the influence of the wealthiest Americans and improve political responsiveness to ordinary citizens. Drawing on extensive data, including surveys and campaign records, Zachary Albert and Raymond J. La Raja largely dispel this myth, offering the first comprehensive portrait to date of small donors in US elections.

Although small donor contributions to high-profile, national races have increased markedly since 2018, the US campaign finance system allows for even larger sums of money from Super PACs and other independent spending groups. Moreover, small donors are mostly similar to their larger contributor counterparts: both are socioeconomically advantaged, strongly partisan, ideologically extreme, and distinct from non-donors. Small donors can also be impulsive: they tend to give mostly to high-profile candidates on the ideological extremes, empowering media celebrities and norm-breakers rather than consensus-builders, and they underinvest in competitive and down-ballot races. Importantly, the candidates who rely most heavily on small donor support are not necessarily better legislators or representatives.

Yet, the story is not entirely bleak. Small donors bring energy and resources, especially for challengers and outsider candidates. The book shows how reforms could channel this energy more productively—by strengthening political parties, emphasizing local representation, and creating systems that broaden participation beyond the most ideological citizens.

Timely, accessible, and grounded in data, Small Donors in US Politics reveals both the promise and the peril of small donor politics—and what it will take to make money in politics serve democracy, not undermine it.
