An updated and more refined version of this graph.
Left to right, the ratio of visits on Hardcore for Nerds received from each state (August-November 2008) to its share of US population (adjusted for broadband penetration). And on the vertical axis, the positive or negative vote-margin in each state for Obama-Biden (Delaware, Hawaii and Illinois have been re-adjusted to 2004 levels). The trend (regression) line has an r-squared value of just under 0.55, which is an expression of how well the date points conform to a linear trend (answer: moderately well).
For example: Pennsylvania (PA) had 1.54 times the number of visits that would be expected from its population size (against the number of readers from the US overall) and broadband penetration, and went for Obama by a margin of 10.37%. It's also quite close to the trend line, meaning it's not an outlier...
Alaska, what's up?
D.C., rock top!
Mississippi, you need more punk...
Addendum: same graph with the readership expressed as visits per 100,000 population (adjusted for broadband penetration) here.
