There is, in fact, a liberal who won't acknowledge that the deficit is a direct result of spending: The guy in this video.
It's exhausting to correct your side's dishonesty. Let me ask you two questions: When was the last time Bush and the Republicans controlled the entire budget process (the wars, tax cuts, Medicare Part D, etc. all included)? What was the budget deficit for that year?
Here are the answers: FY 2007, and $161 billion. That's still too high, and Republicans were not as fiscally responsible as they should have been, but it simply does not compare to the avalanche that Pelosi/Reid/Obama have engineered. But thanks for playing.
