The "red shift" between exit poll margins of error and "actual" vote counts is based on weighted poll results. The raw data has already been adjusted for various factors, and the prediction is issued. Then, in selected cases, the vote counts fall outside the margins of error.


Until 2004, exit polls worked in America as well as they did elsewhere. It was in 2004 that polling companies started adjusting their results to match the vote counts. Which is a practice that stinks to heaven, imho.
