1) State and national polls polls are adjusted assuming that
70% of undecided voters will vote for Kerry.
2) State polls are weighted by its voting percentage of the
total nationwide vote for the last 3 elections.
3) Third party candidates not considered.
4) I assume Diebold/ES&S DO NOT steal it for Bush, so take
these results with a BBV grain of salt.
5) The analysis is only as good as the quality of polling
data. The 13 national polls include CNN/Gallup, Fox and IBD.
It is fair to say that they have a tendency to pull Kerry's
average numbers down somewhat. The good news is that the Kerry
total % based on the state polls appears to track with the
national polls. Any divergence would raise eyebrows.
6) A caveat: State polls may be somewhat outdated. National
polls are probably more current.
Over the last three presidential elections:
Total Votes (millions):
Dem: 138.75 (52.60%)
Rep: 125.03 (47.4%)
Monte Carlo simulation uses random numbers applied to
probabilities of uncertain events to generate a range of
potential outcome scenarios. For this analysis, I used the
latest state poll numbers to generate a simulated election
probability analysis.
In this case, an "event" is Kerry's share of a
state's popular vote. An "outcome" is the simulated
probability of Kerry winning the election, based on his total
electoral votes.
For example, if we run the simulation 10 times and Kerry's
electoral vote total exceeds 269 votes in 9 of the 10
simulations, we can estimate that he has about a 90%
probability of winning the election. I assume each poll has a
margin of error of +/-4%. I also assume an equal distribution
of outcomes around the mean polling estimate.
We assign Kerry has a probability of winning each state, for
example:
Kansas: .001
New York: .999
Florida: .807
The probabilities are determined by the latest polling
numbers.
For instance, if the latest Kansas poll is 60% for Bush, 40%
Kerry, then Kerry has an approximate 1 in 1,000 chance of
winning the state.
On the other hand, if Kerry is ahead by 5% in Florida, then he
has an 80.7% probability of winning the state.
Using Excel's random generator function, each calculation
returns a random number X between 0 and 1. If X is less than
the probability of Kerry winning the state, the state goes to
Kerry, otherwise it goes to Bush.
For instance, if X = .72 for Florida, then Kerry wins the
state. The random number X= .72 is LESS than the .807
probability that Kerry will win FL, based on the latest polls
which have him leading by 5%.
The simulation runs for all states. The electoral votes are
summed for those states which fall in Kerry's column.
Remember, we assume that Kerry's polling percentages numbers
are increased by allocating 70% of the state's undecided vote
in the simulation.
For example, assume Kerry is leading in a state by 46%-44%.
Allocating 70% of the 10% undecided voters to Kery adds 7% to
his total, so the adjusted projection is Kerry 53%-47%.
