Statistics say that even a sample of about 40 is very accurate--if it is truly conducted randomly among the total sample population. 400 would be plenty enough to get an accurate picture of what SC voters are thinking at this particular point in time.
The predictive value of such polls for a very volatile contest a few weeks away is highly inaccurate. About the most you could infer is that Obama is increasingly his lead. In other words he is trending up.
To sum up, the direction of the polls are probably highly accurate, but the magnitude of the lead varies so much as to be virtually meaningless.
