Asians and hispanics are intermarrying with whites too quickly for there to be solidly white/minority blocs by mid-century.
What about the Blacks?
Some are, but they are a smallish sliver.
One thing that interesting in interacial couples- are the whites multiculturally liberal, or the minorities conservatives trying to intergenerationally climb?
A lot of Whites I know that are in interracial couplings tend to be more moderate and liberal than normal. Then again I'm a Filipino guy who has dated mostly White chicks, they weren't that political so I couldn't tell from my stance.
