Social Movements and U.S. Political Parties: Evolutionary and Revolutionary ChangeSocial movements are asking how organized and mobilized masses address power and power holders. Parties are among these power holders, but more widespread concerns about fascism have led to questions about the viability and responsibilities of parties. Therefore, we aim to understand the relationship between these two entities. We begin by differentiating between social movements seeking evolutionary and revolutionary change. Evolutionary change includes movements working within and towards maintaining fundamental governing and organizing structures (e.g., Christian Conservatism and the Tea Party). Revolutionary change describes movements working to fundamentally change power structures and underlying power distribution (e.g., Black Lives Matter and White Nationalism). Others still cross these boundaries in complex ways (Civil, Women’s, and LGBTQ+ Rights). And as for parties, we point back to the initial questions — who is holding power in parties and how might it be democratically distributed and resistant to fascism and authoritarianism? We highlight critical scholarship, that which has long addressed white supremacy, patriarchy, ableism, trans- and homophobia, as key to advancing these conversations and the causes of marginalized communities. Change is less about new ideas and more about new considerations of communities with longstanding investments in the work of liberation.
