The measurements should be against total GDP rather than a simple year to year comparison. It should be government spending as a percentage of the US economy.
Under Regan, Clinton, Bush 43, even LBJ and Nixon, the economy was growing briskly during most years. The same is not true for 0bama, where, like Carter, there has been stagflation. So increased spending in a stagnant economy is actual growth in spending, whereas increased spending in a growing economy may simply be keeping pace.
0bama's spending increases have not been financed by an improving economy, but instead have been paid for entirely by increasing the national debt.
