You have just received the results of the National Exit Poll
of 13047 respondents. They show that Kerry is the winner by
50.69% - 47.77%. This closely matches the pre-election polls,
after adjusting for an expected undecided voter allocation
(2-1 for Kerry).
It's your job to adjust the weightings and fine-tune the
results, based on your best interpretation of the latest
demographic data.
This is the the Exit Poll for the Party-ID category:
PARTY ID Mix Bush Kerry Nader
Dem 38% 9% 90% 1% 100.0%
Repub 35% 92% 7% 1% 100.0%
Indep 27% 45% 52% 3% 100.0%
100% 47.77% 50.69% 1.54% 100.0%
You notice that the PartyID mix differs slightly from the two
prior elections, in which the weightings were 39 Dem/35 Rep
/26 Independent.
1) Do you change the mix slightly to 39/35/26, leaving the
voting percentages intact?
PARTY ID Mix Bush Kerry Nader
Dem 39% 9% 90% 1% 100.0%
Repub 35% 92% 7% 1% 100.0%
Indep 26% 45% 52% 3% 100.0%
100% 47.41% 51.07% 1.52% 100.0%
or
2) Do you change the PartyID mix to 37/37/26, even though this
is at variance with the two prior elections?
Do you also change the voting percentages, even though there
is a 1.0% margin of error in an Exit Poll of 13047
respondents?
Making these adjustments will reverse the Exit Poll weighted
popular vote from 51-48% Kerry to 51-48% Bush.
