Also Obama is losing in Northern Virginia and the Tidwater, but tied in Southwest Virgina???
It's probably a bad poll, but Northern Virginia could theoretically include more than the three counties Obama won, and it's also possible that Obama could make minor gains in the Southwest (though not nearly enough to win the region, of course).
Sample size of just under 700 for the whole state = tiny subsamples in the regions. So the fact that those are wrong doesn't say much about the poll as a whole.
Just toss it in the average.
