Teixeira is by no means alone. The New Republic’s John Judis, who collaborated with Teixeira on the 2001 book The Emerging Democratic Majority, wrote an article titled “America The Liberal” the day after the November 4, 2008, election. Judis made a similarly well-argued case that the election of Obama “is the culmination of a Democratic realignment that began in the 1990s. … The country is no longer ‘America the conservative.’ And, if Obama acts shrewdly to consolidate this new majority, we may soon be ‘America the liberal’.”
On April 9, 2009, Emory political scientist Alan Abramowitz published a paper arguing that Obama’s victory “was made possible by long-term changes in the composition of the American electorate, especially the growing voting power of African-Americans, Hispanics, and other nonwhites. As a result of these demographic changes, the Democratic Party enjoys a large advantage over the Republican Party in the size of its electoral base — an advantage that is almost certain to continue growing for the foreseeable future.”
All three authors make overlapping and similar cases.
