Consider this a public service announcement. Do not pay attention to exit polls on the night of a presidential election. For the full explanation, check out Nate Silver, but here’s a crib sheet.
(1) The margin of error is 50-90% higher for exit polls than for regular polls. That means a margin of error as large as 7 or 8 points, a huge number. (2) Exit polling was badly wrong during the 2000 and 2004 presidential elections, as well as many of the 2008 primaries. (3) The folks who willingly participate in exit polls are never truly random; this time around, they are more likely to be Democrats than Republicans because of Democrats’ well-established greater enthusiasm for their candidate. (4) A whole host of other reasons.
The solution? Breathe deep and know that you’ll have some serious results from all over the country by 8 pm.
