D.C. is on the bottom of the list, but just to remove it from the rankings; it gets the most funding. It should be dark red on your map (I think), not dark blue.
What does this correlate with, exactly? Out of curiosity.
There appears to be a fairly strong positive correlation between the money they get back and whether they voted Bush, and a negative correlation with their population.
I suppose that is fairly logical, but the correlation seems to be more population than politics (hence Georgia, Texas, and Rhode Island), although it doesn't explain Vermont.
Is there any information on what formula they use to calculate the fundings?
