You aren't adjusting for inflation or relative GDP, so that's mistake #1. Second, over the last years the US deficit has averaged a bit over 3% of GDP, making this years deficit of 2.8% of GDP lower than average.

That's right, Obama is thriftier this year than the average since Reagan came into office, and many of those years were much brighter economically than now.
As shown by my previously linked chart the economy is still well below its potential output. Additionally, inflation is low, potential employment far below where it could be, and wages are stagnant. The economy is not doing well, it is simply doing better than it was before.
I don't care what politicians say, and neither should you. Obama has brought down the deficit far too quickly in light of the reality of our economic situation.
