"Nationally, his increase in black support was only three percentage points (from 8% in 2000 to 11%). In terms of the national popular vote, black voters were marginal for Bush. Hispanic voters - where Bush went from 35% to 41% - were much more influential here.
However, state returns in the two biggest battleground states tell a different story. In terms of the electoral vote - especially in Ohio - increased black support for Bush was key. Republicans bought air time on black radio stations in eight or so battleground states, and it paid off in increased black support - despite an historic black voter turnout, which Republicans typically fear."
