John Judis, coauthor with Ruy Teixeira of the best-selling The Emerging Democratic Majority, has recanted. Growing numbers of non-white Americans don't, he now believes, guarantee a Democratic majority after all. See his reasoning:
The U.S. census makes a critical assumption that undermines its predictions of a majority-nonwhite country. It projects that the same percentage of people who currently identify themselves as “Latino” or “Asian” will continue to claim those identities in future generations. In reality, that’s highly unlikely. History shows that as ethnic groups assimilate into American culture, they increasingly identify themselves as “white.”Large numbers of both voted for one Donald J. Trump ... go figure.
Whiteness is not a genetic category, after all; it’s a social and political construct that relies on perception and prejudice. A century ago, Irish, Italians, and Jews were not seen as whites. (snip) But by the time Truman became president, all those immigrant groups were considered “white.” There’s no reason to imagine that Latinos and Asians won’t follow much the same pattern.
In fact, it’s already happening. In the 2010 Census, 53 percent of Latinos identified as “white,” as did more than half of Asian Americans of mixed parentage. In future generations, those percentages are almost certain to grow. According to a recent Pew study, more than one-quarter of Latinos and Asians marry non-Latinos and non-Asians, and that number will surely continue to climb over the generations.
