illinois 25.7% of it's $822 bilion dollar (spending) budget is a much larger number then South Carolina's 32.4% of a $23 billion dollar (spending) budget. (2013 numbers for both states, most current available.)
I couldn't find the federal $ amount in SC's budget. But Illinois lists $84Billion as Federal money on the revenue in it's budget. (Which it list's as part of agency appropriations.) Which would be far less the 25.7% in the article.
