Sorry I missed this back in May:
[Investors Business Daily] compared average job growth, unemployment, changes in housing prices, per capita income and GDP growth, and gas prices for the 22 states that voted for John McCain in 2008 and the 28 states that voted for Obama .
On every indicator but one, blue states have done worse, on average, than red states.
In addition, IBD looked at the economic performance of 11 states that Real Clear Politics lists as tossups for the 2012 presidential election. Many of these purple battleground states have fared far worse than the country as a whole during the past three years....
