Insurance and liberalism

Rick Perry just joined the presidential race. The man to beat is Mitt Romney. Coincidentally Perry is the governor of the state with the highest percentage of uninsured and Romney is the former governor of the lowest percentage of uninsured. In 2009, 28.5% of Texans under the age of 65 were uninsured. In Massachusetts that number was 5.2. In 2010 this number fell significantly but these numbers are not available from the Census Bureau. The overall number of uninsured was about 2%.
Unsurprisingly there's a pretty good relation between politics and uninsured. I used the margin of Obama's win margin (a negative number if he lost) in 2008. He won MA by 25.81% and lost Texas by 15.06%. His biggest wins were DC and Hawaii, 85.92% and 45.26%. I threw out DC because it's uninsured numbers are complicated by the federal government and it's margin is incredibly high (the uninsured under 65 is below the US average of 18.8% at 13.7%.) His biggest loss was in Wyoming at -32.34%, were 18.1% are uninsured.
The trendline's formula is -28.05ln(x)+80.899. The r^2 value is .19086. This isn't particularly high but the downward slope is high enough to make this significant
