The Crucial Role of Race in Twenty-First Century US Political Realignment.

Traditional realignment theory has fallen out of fashion among political scientists, yet the popular press talk about political realignments with great regularity. However, in this research note we show that political science should reconsider realignment theory because over the last decade American politics has dramatically realigned—but only for white Americans. Specifically, we demonstrate that income has gone from a highly polarizing factor to one in which there is little to no polarization at all, while at the same time education polarization has increased dramatically to become the prominent demographic cleavage in the white segment of the electorate. However, no such realignment has occurred among Black or Latino voters. These differences across racial groups show how it is essential to consider race in theories of realignment, particularly because of the different experiences across racial groups. Realignment theory is quite viable in the twenty-first century, but the lens of race is the key to seeing the white realignment. [ABSTRACT FROM AUTHOR]
