You can spin this finding in several very different ways. Way one: The Democrats have done little to attract white voters, and instead showed a strong bias in favor of minorities. Way two: The Republicans have done little to attract minority voters, and instead showed a strong bias in favor of whites. Way three: Party platforms and ideologies appeal to different groups, it's daddy party vs. mommy party. Way four: Ethnic cleansing in the Democrat Party is driving out the whites (I hope I'm joking). Way five: Minorities don't want to be in a party with lots of whites. Etcetera.
