Here is a run of the Exit Poll Response Optimizer for what I
believe to be the most likely and plausible scenario.
INPUT
1. Target: Kerry wins 52.5% of 2-party vote
2. Response = R = 53% (wtd average)
3. Alpha = K/B =.98 (wtd average)
(Kerry voters slightly more reluctant 49 Kerry/50 Bush)
I believe Repubs for Kerry were intimidated.
It makes more sense intuitively AND anecdotally.
E-M says that Alpha = 56/50 =1.12
OUTPUT:
4. Kerry wins Exit Poll with 51.46% of 2-party vote
5. Total 2 party vote (121mm):
Kerry 63.52mm, Bush 57.47mm
6. Avg WPE: 2.08%
7. Exit Poll Response:
Ranges from 48% (High Bush precincts) to 52.5% (Non-partisan)
to 58% (High Kerry).
EXIT POLL RESPONSE OPTIMIZATION MODEL
6/9/05 10:21 AM
Objective: Determine values of constrained variables required
to derive a target Kerry/Bush percentage split using aggregate
exit poll response data.
Precinct Variables Range Constraints:
1-Response: within (Min, Max) and equal to weighted avg
rate.
2-Kerry win percentage:within (Min, Max).
3-Alpha (K/B): within (Min, Max) and equal to weighted
average.
4-WPE within E-M actuals or (Min, Max).

Kerry 2-party vote 52.50%
Bush 2-party vote 47.50%
