It's gone to diversity. Recently Hillsdale College published an article on diversity, citizenship and immigration, taken from a speech given this past April. Well worth a read.
Does Diversity Really Unite Us? Citizenship and Immigration

A few short quotes:
"Progressive liberalism no longer views self-preservation as a rational goal of the nation-state. Rather, it insists that self-preservation and national security must be subordinate to openness and diversity."
"In support of all this, we are asked to believe something incredible: that the American character is defined only by its unlimited acceptance of diversity. A defined American character—devotion to republican principles, republican virtue, the habits and manners of free citizens, self-reliance—would in that case be impermissibly exclusive, and thus impermissibly American."
"Our progressive politicians and opinion leaders proclaim their commitment to diversity almost daily, chanting the same refrain: 'Diversity is our strength.' This is the gospel according to political correctness ... But greater diversity means inevitably that we have less in common, and the more we encourage diversity the less we honor the common good."
