It kinda sorta makes sense because it's true. Extending the tax rates has a negative impact on debt and the deficit and would therefore been included in the CBO score for the stimulus bill. A rough estimate for the "middle class" tax cut portion of this deal is about $383 billion. If you add that to the $787 billion stimulus cost, you are over $1.1 trillion. Given that the stimulus bill was whittled down to $787 to appease "centrist" Senators so it could pass, there is simply no basis for the argument that a $1.1 trillion bill would pass when they balked at $830 billion.
And I know you love to criticize Obama, but he actually got a deal done that most people are grudgingly agreeing with. Typically, that's called "leadership" and "bipartisanship." It's not necessarily my taste, but moderate independents like yourself usually eat that shit up. What gives?
