Could you explain that chart a little more, please.
15 , 30, 45% of GDP etc.
I got the original numbers from the budget spreadsheets here, and you can use the link to get both the raw numbers for spending, taxes, deficit, and gdp, or you can also get the budget numbers as a percentage of gdp to show just how serious they are. Next, I put them into this table and plotted them into the chart.
