This is an interesting statistical situation. I have cross posted in the politics forum as I am not sure if this has more to do with politics or mathematics.
So, let's suppose we find the average IQ of each American state. Now lets assign a number to each state, 1 for highest IQ, 2 for second highest, 3 for third highest, and so on.
Now, suppose that the number of states that Kerry won is x. Let's define K the total number of 'points', where you sum all the points from each state he won. So If Kerry only won two states, and say these states ranked 23th and 45th in terms of average IQ, then K would equal 68.
If there was no correlation between average IQ and which presidential candidate won the state, then the probability distribution for K would be:
P(K<x*(x+1)/2) = 0
P(K=x*(x+1)/2) = 1/(50 choose x)
P(K=x*(x+1)/2+1) = 1/(50 choose x)
P(K=x*(x+1)/2+2) = 2/(50 choose x)
P(K=x*(x+1)/2+3) = 3/(50 choose x)
P(K=x*(x+1)/2+4) = 4/(50 choose x)
P(K=x*(x+1)/2+5) = 6/(50 choose x)
P(K=x*(x+1)/2+6) = 7/(50 choose x)
P(K=x*(x+1)/2+7) = 10/(50 choose x)
P(K=x*(x+1)/2+8) = 11/(50 choose x)
P(K=x*(x+1)/2+9) = 16/(50 choose x)
and so on
Now according to this source http://www.mindfully.org/Reform/2004/US-Election-IQ2004.htm
x=19
Therefore:
P(K<190) = 0
P(K=190) = 1/(50 choose 19)
P(K=191) = 1/(50 choose 19)
P(K=192) = 2/(50 choose 19)
P(K=193) = 3/(50 choose 19)
P(K=194) = 4/(50 choose 19)
P(K=195) = 6/(50 choose 19)
P(K=196) = 7/(50 choose 19)
P(K=197) = 10/(50 choose 19)
P(K=198) = 11/(50 choose 19)
P(K=199) = 16/(50 choose 19)
and so on
Which therefore makes the probability that K<200 :
P(K<200) = 61/30405943383200
= .000000000002006...
But according to this source, K=199
Now one of three things must be true:
1. It is a miraculous fluke that it has happened this way
2. My assumption that there is no correlation is incorrect
3. The data from my source is incorrect
I'm going with number 2. Even if number 3 is the case, the data would have to be totally way off before number 2 does not have to be the case anymore.
So here is my open question, why the correlation?
For those interested in how I found out the probability distribution, I will show if you want, I find it interesting. It brings rise to the series (1 1 2 3 4 6 7 10 11 16 17 23 24 33 34 44 45 60 61 77 78 .... )
Here is the data I used.

IO numbers are from IQ And The Wealth Of Nations, although not in the current edition. Tests and data by Raven's APT, and The Test Agency, one of the UK's leading publishers and distributors of psychometric tests. Data was published in The Economist and the St Petersburg Times, though this does not mean it should be taken as fact.
So, let's suppose we find the average IQ of each American state. Now lets assign a number to each state, 1 for highest IQ, 2 for second highest, 3 for third highest, and so on.
Now, suppose that the number of states that Kerry won is x. Let's define K the total number of 'points', where you sum all the points from each state he won. So If Kerry only won two states, and say these states ranked 23th and 45th in terms of average IQ, then K would equal 68.
If there was no correlation between average IQ and which presidential candidate won the state, then the probability distribution for K would be:
P(K<x*(x+1)/2) = 0
P(K=x*(x+1)/2) = 1/(50 choose x)
P(K=x*(x+1)/2+1) = 1/(50 choose x)
P(K=x*(x+1)/2+2) = 2/(50 choose x)
P(K=x*(x+1)/2+3) = 3/(50 choose x)
P(K=x*(x+1)/2+4) = 4/(50 choose x)
P(K=x*(x+1)/2+5) = 6/(50 choose x)
P(K=x*(x+1)/2+6) = 7/(50 choose x)
P(K=x*(x+1)/2+7) = 10/(50 choose x)
P(K=x*(x+1)/2+8) = 11/(50 choose x)
P(K=x*(x+1)/2+9) = 16/(50 choose x)
and so on
Now according to this source http://www.mindfully.org/Reform/2004/US-Election-IQ2004.htm
x=19
Therefore:
P(K<190) = 0
P(K=190) = 1/(50 choose 19)
P(K=191) = 1/(50 choose 19)
P(K=192) = 2/(50 choose 19)
P(K=193) = 3/(50 choose 19)
P(K=194) = 4/(50 choose 19)
P(K=195) = 6/(50 choose 19)
P(K=196) = 7/(50 choose 19)
P(K=197) = 10/(50 choose 19)
P(K=198) = 11/(50 choose 19)
P(K=199) = 16/(50 choose 19)
and so on
Which therefore makes the probability that K<200 :
P(K<200) = 61/30405943383200
= .000000000002006...
But according to this source, K=199
