Blacks are pretty heavily overrepresented among people getting food stamps.
However, the more interesting question is why you care so much about the racial-politics angle that you're bringing up the "see white people get welfare too!"
hint: conservatives don't dislike welfare because it's good for black people, and we hate black people, so we want to take it away from them. Even if that is the only explanation your feeble, prejudiced, racially-obsessed mind can come up with.
