Why not?
If they want to assume rBr, we can assume the more plausible
rKr hypothesis.
If you were a Republican, wouldn't you be somewhat reluctant
to tell someone you just voted for Kerry, especially when
there are fellow church-goers nearby?
EXIT POLL RESPONSE OPTIMIZATION MODEL
6/12/05 9:04 PM
Objective:
Calculate the precinct partisanship response required in the
13047 National Exit poll (which Kerry won by 50.8-48.2%) for
Kerry to win 52.50% of the 2-party vote, assuming a reluctant
Kerry responder.
Given the following:
1) Reluctant Kerry Responder (rKr)
Alpha = .96 (48 Kerry responders for every 50 Bush exit poll
responders).
2)53% aggregate response rate
3)Edison- Mitofsky partisanship precinct mix
The Optimizer produced the following results which are very
close to the 13047 respondent National Exit Poll:
Kerry 51.52%
Bush 48.48%
The corresponding winning Kerry margin based on the
52.50%-47.50% split of 121 million total votes is:
Kerry 63.52 mm
Bush 57.47 mm
