It needs to reflect reality, and the reality is that close to 30% of Virginia's population lives in northern Virginia.

So if the poll is considered skewed because it reflects that reality, then the comment is wrong. I don't know the percent the poll listed as coming from northern Virginia.

If the poll has 50% of the respondents coming from northern Virginia, then it is skewed...if the poll lists 30%, then it is not skewed.
