Okay, here's a link to a special report by the Tax Foundation (a very conservative anti-tax organization, btw). Line up the states by the ratio of federal spending to taxes paid. The highest ratios? New Mexico, Alaska, Mississippi, Alabama, the Dakotas, Virginia, West Virginia, Montana, Idaho. The lowest ratios? New York, California, Minnesota, Illinois, New Jersey, Connecticut, Mass. The correlation isn't perfect (e.g. Texas is receives slightly less in federal expenditures than it pays in taxes, and obviously, it's pretty durned red. Iowa is the reverse), but it's pretty strong. A little googling will reveal a number of additional citations.
