McCAIN CAMPAIGN MEMO: READING THE EXIT POLLS
BILL McINTURFF, INTERNAL POLLSTER
Here are the key points to keep in mind when the exit poll data starts being leaked:
1. Historically, exit polls have tended to overstate the Democratic vote.
2. The exit polls are likely to overstate the Obama vote because Obama voters are more likely to participate in the exit poll.
3. The exit polls have tended to skew most Democratic in years where there is high turnout and high vote interest like in 1992 and 2004.
4. It is not just the national exit poll that skews Democratic, but each of the state exit polls also suffers from the same Democratic leanings.
5. The results of the exit polls are also influenced by the demographics of the voters who conduct the exit polls.
The recent Fox News survey showed that 46% of Obama voters said they were very likely to participate in the exit polls, while just 35% of McCain supporters are.
In fact, even the 2004 exit poll report noted that higher turnout nationally and higher levels of voter interest in both 1992 and 2004 correlated with greater Within Precinct Error.
Conclusions
Based on the previous exit poll results, we should expect once again that Tuesday's exit poll data could overstate the Obama vote and under represent the McCain vote.
It is important that the campaign make sure the media realizes this, so that when the exit polls do leak, people do not overreact to the early exit poll data. Rather than looking at the exit polls, we should wait until we start seeing actual election results from key precincts and counties to gauge who won the election.
