be manipulated. what i'm saying is that honest polling can be accurate with a small sample. usually after a small threshold has been reached, a larger sample does not give more accuracy, but continues to show the same trend.
with 30% reporting, there is more than an ample sample to show how the trend would go. they used to be able to call elections with a small sample on the day of voting precisely because this holds true.
I believe that they quit calling elections based on early returns because the vote flipping machines now kick in after about 30% and things don't turn out they way the early trends point.
with about 30% reported yesterday, Cuccinelli was ahead 50 something % to 30 something %. after that the vote flipping machine kicked in and mccaulif started steadily gaining until, at the very end, he went ahead and "won" the election.
