Perhaps in total but certainly not as a percentage of the population.Whites account for nearly 65% of the population-blacks about 12%.
Obviously population wise its more prevalent in the black community but the fact of the matter is more whites are on welfare, so its not totally a minority issue, its an economic issue. As far as McCain getting support from the troops, you know as well do i that there was a certain candidate a few months back who had more support then then either of them.
