Just in case you don't think the federal tax data was impressive enough, I prepared a map comparing the Gross State Product per capita across the states. These are the 15 states that have the lowest GSP. Not surprisingly, all but one are red. 15 of the 19 blue states are in the top 25, and if you look at the average GSPs, you see where the money is coming from.
Data were obtained from the Bureau of Economic Analysis www.bea.gov,
GSP data for 2004 and from the U.S. Census bureau, www.census.gov,
population statistics from 2004.
