Weighting our final NC Poll

Our final North Carolina poll will be released within the next few hours. A big decision for pollsters on this one is how to weight for race. 28% of the Democratic primary electorate in 2000 was black, and in 2004 it was 32%. But over 40% of early voters were.

Obviously how you choose to nail down that figure can have a pretty significant effect on your Presidential numbers when the electorate is so polarized along racial lines.

We settled on 35%. We asked folks who were polled if they had voted early. Taking all of the respondents in our poll, if 40% of those who voted early were black then 35% of the population as a whole was.

I don't know if that's the best or most perfect way to do it but it is at least a rational decision based on the data we have.
