If it’s fair for George Will, Pat Buchanan and Rush Limbaugh to assume that Colin Powell is voting for Obama just because they’re both black, it’s equally fair to assume that Will, Buchanan and Limbaugh are voting for McCain just because he’s white.  Which means they are admitting that they’re not voting for Obama because he’s black.
