Click the picture to enlarge. Further explanation (kinda technical) added below.
I've been wanting to do this for a while...
From left to right is the distribution of Hardcore for Nerds readers from the United States, in terms of the percentage of the readership (via Google Analytics) from each state, relative to its percentage of the population overall. It is expressed in terms of % difference: for example, New York on the extreme left makes up 6.31% of the US population and 10.31% of visits to this blog from the US, hence a percentage point difference of almost exactly (+)4%.
The clear columns going up and down are the distribution of red (down) and blue (up) states, according to FiveThirtyEight.com as of today [Friday Oct. 3rd]. So while Florida (second from the extreme right) may switch to a red state in the end, Alaska on the left is not realistically going to switch to blue. You can adjust the exact data points according to whatever predictions you follow, but the overall trend is clear.
And also, I suppose, fairly obvious to begin with. However, this is the statistical proof* that Hardcore for Nerds is a blue state blog...
* as a politics student and someone who is generally very good at mathematics, I absolutely do not stand over the validity of this exercise in any way.
EXPLANATION: Basically this graph shows a strong correlation between whether a state has above or below average readership of the blog (as against its share of the national population) and whether it is a 'red' or 'blue' state in current electoral terms. (Blue for Democratic - Obama - and red for Republican - McCain, incidentally in complete reversion of the traditional British-Irish/European political scheme, which assigns blue for conservative and red for left-wing or socialist)
The switch from blue to red occurs almost exactly with the point that readership drops from exactly average (no difference between % of readership and % of population) to below average. With the exception of Alaska, all the above-average readership states are blue, leading to the statement above.
On the below-average side, it's a little bit more complicated. Some of them, like Delaware and (I guess) Washington, are firmly in the blue camp. Others are more easily identified as swing states: Ohio, Michigan, Florida and New Mexico.
Please note that the order of the states on the graph is in decreasing positive (and then increasing negative) magnitude of difference between % of readership and % of population. They are not adjusted for population. So a large magnitude of difference does not necessarily represent a huge disparity of readership; rather it represents a relative measure, a function of a) the population size and b) the actual disparity of readership per head.
Therefore the fact of whether a state is close or far away from the centre of the graph (low % difference) changes its significance according to where the state stands in terms of its population size. States that are large should be closer to the edges - if they are not, then they have a more average level of readership than those that are; and small states should be in the centre; if they are not, then they have a high disparity (for example Connecticut, which probably has a lot to do with this blog.)
For bonus marks, you can tell me why this means, statistically speaking, that the three swing states on the far right could be expected to be in that position, or - to phrase the question differently, and a slight hint - why the states in that position could be expected to be (important) swing ones?
A few more notes:
Population data from Wikipedia, of course.
US readership comprises 48% of Hardcore for Nerds readership during the period July 25th-October 2nd, with a total of 7,297 visits.
'Not stated' made up 1.45% of visits, while other US territories make up 1.44% of the total population.
