Over the nearly 250-year history of the United States, there have been many moments of political and social discord that have tested the strength and depth of the American character, and such crises have often led to positive social changes that have expanded the American community through passage of constitutional amendments and laws that expanded voting rights, defined and expanded citizenship, codified racial and gender equality, protected workers’ rights, increased economic opportunity, and provided greater access to equal educational opportunities, among many other advances. Yet, it is also the case that the American past never fully recedes from the body politic; there has been an ongoing tug-of-war between forces seeking to overturn social and economic progress and those forces working to solidify and expand rights that have often been rights in name only. What has occurred in the past is never excised from national memory and can reappear in virulent forms; the immigration-restrictionist policies and actions that characterized the darkest aspects of the Americanization movement in the early decades of the twentieth century have come full circle in the American presidency of Donald J. Trump.
