blacks 79-21 Obama. Slight reverse bradley effect?
Sample size of 60. People need to remember subsamples are not polls in and of themselves.
True but it does affect the topline doesnt it.
A subsample only matters to the overall poll if they do weighting on the subsample. In theory the participants are random and then everything we see as a special subsample is completely meaningless. The black/white vote may be off, but then so may be the the votes of of the 60-68 year old men who color their hair. It all averages out to within the overall MOE.
Now if in this poll they take the vote of blacks and inflate/deflate it to account for sampling difficulties, then it matters.
