re: 88%
Actually, I got 88.84%, given your figures, but the missing 2% of miscellaneous voters probably squared that:
% of Pop % Bush Votes White vote as % of all
White 77% 58% 44.66% 88.84%
Black 11% 11% 1.21%
Latinos 8% 44% 3.52%
Asians 2% 44% 0.88%
Total 98% 50%
% of Pop % Kerry Votes White vote as % of all
White 77% 42% 32.34% 67.76%
Black 11% 89% 9.79%
Latinos 8% 56% 4.48%
Asians 2% 56% 1.12%
Total 98% 48%
Note that Kerry got 67% of his vote from whites, too. - Has to be so because they're such a large part of the electorate.
