Many contend that U.S. state parties are increasingly polarized and nationalized, meaning that they have adopted divergent positions matching their national counterparts’ positions. Such trends reflect a transformation of America's historically decentralized party system. Yet, the precise timing of these related trends—as well as the mechanisms underpinning them—remain unclear. We assess these dynamics using a novel data set of 1,783 state party platforms between 1918 and 2017. Applying tools from automated and manual content analysis, we document a dramatic divergence in the topics emphasized by Democrats and Republicans starting in the mid-1990s, just as congressional speech became polarized. During this period, cross-state differences in each party's agenda decreased and regional/sectoral issues became less prominent, suggesting tight connections between polarization, nationalization, and state agendas. We also find that innovative phrases increasingly debut in state (not national) platforms. Overall, the evidence undercuts claims of top-down polarization emanating from national party leaders in Washington, DC. Polarization at the state and federal levels coincided with the development of an integrated network of activists spanning multiple levels of the polity.

After defeat in the Civil War, the white South used time as a tool of political oppression. Myths of the “Old South” and the “Lost Cause” distorted history and public memory; vagrancy laws and labor regulations controlled the time of the newly free; grandfather clauses distributed rights based on past conditions; and attacks on education, labor, and democratic rights undermined progress in the “New South.” In this article, I show that Black southerners also recognized the political value of time. My source for their sentiments is the Colored Conventions Movement. From 1865 to 1900, dozens of conventions gathered in the South, at a significantly higher rate than in other regions. Delegates deployed temporal rhetoric of the past, present, and future in pursuit of equality and justice by (1) publicly recounting African American history and national contributions to counter white narratives, (2) arguing that emancipation was a new founding moment and the present a time of ongoing crisis, and (3) demanding labor and education rights to secure the future. Scholars of American political development often consider time in studies of institutional change; we should also explore the use of time as a political tool and how temporality illuminates American racial dynamics.

The American knowledge economy (AKE) is not a foreordained transition in the organization of economic production, nor is it a form of political economy shaped predominately by the political demands of highly educated workers. It is a politically generated consensus for producing economic prosperity and economic advantage over other nations in which intellectual property (IP), and the businesses that produce it, play a leading role. The history of AKE development reveals as much. In the AKE's formative period, from 1980 to 1994, IP producers and a faction of neoliberal Democrats (the “Atari Democrats”), not decisive middle-class voters, played a pivotal role in reconfiguring institutions of American political economy to hasten the AKE transition. Their vision of AKE development inherently complicated the Democratic Party's attitude toward rising market power and continues to shape contemporary disputes within the party over antitrust enforcement and the validity of the AKE project itself.
