Want to know how the deficit got this bad? From the Center on Budget and Policy Priorities:
Just two policies dating from the Bush Administration -- tax cuts and the wars in Iraq and Afghanistan -- accounted for over $500 billion of the deficit in 2009 and will account for almost $7 trillion in deficits in 2009 through 2019, including the associated debt-service costs. (The prescription drug benefit enacted in 2003 accounts for further substantial increases in deficits and debt, which we are unable to quantify due to data limitations.) These impacts easily dwarf the stimulus and financial rescues. Furthermore, unlike those temporary costs, these inherited policies (especially the tax cuts and the drug benefit) do not fade away as the economy recovers.
Without Bush and the economic downturn, the budget would be roughly in balance over the next decade.
