A compelling exploration of concrete strategies to reduce partisan animosity by building on what Democrats and Republicans have in common.  
 
One of the defining features of twenty-first-century American politics is the rise of affective polarization: Americans increasingly not only disagree with those from the other party but distrust and dislike them as well. This has toxic downstream consequences for both politics and social relationships. Is there any solution?  
 
Our Common Bonds shows that—although there is no silver bullet that will eradicate partisan animosity—there are concrete interventions that can reduce it. Matthew Levendusky argues that partisan animosity stems in part from partisans’ misperceptions of one another. Democrats and Republicans think they have nothing in common, but this is not true. Drawing on survey and experimental evidence, the book shows that it is possible to help partisans reframe the lens through which they evaluate the out-party by priming commonalities—specifically, shared identities outside of politics, cross-party friendships, and common issue positions and values identified through civil cross-party dialogue.  Doing so lessons partisan animosity, and it can even reduce ideological polarization. The book discusses what these findings mean for real-world efforts to bridge the partisan divide.   

An unflinching examination of the effects and boundaries of partisan animosity.

For generations, experts argued that American politics needed cohesive parties to function effectively. Now many fear that strong partisan views, particularly hostility to the opposing party, are damaging democracy. Is partisanship as dangerous as we fear it is?

To provide an answer, this book offers a nuanced evaluation of when and how partisan animosity matters in today’s highly charged, dynamic political environment, drawing on panel data from some of the most tumultuous years in recent American history, 2019 through 2021. The authors show that partisanship powerfully shapes political behaviors, but its effects are conditional, not constant. Instead, it is most powerful when politicians send clear signals and when an issue is unlikely to bring direct personal consequences. In the absence of these conditions, other factors often dominate decision-making.

The authors argue that while partisan hostility has degraded US politics—for example, politicizing previously non-political issues and undermining compromise—it is not in itself an existential threat. As their research shows, the future of American democracy depends on how politicians, more than ordinary voters, behave.
