Stimulus math

I think I've raised this point before, but this can't be repeated enough:

...The CBO, to its credit, has been fairly forthcoming about its methods and their limitations. In response to a question at a speech earlier this month, CBO director Doug Elmendorf laid out the CBO's methodology pretty clearly, describing the his office's frequent, legally-required stimulus reports as "repeating the same exercises we [aleady] did rather than an independent check on it." CBO tweaks its models on the input side, he says—adjusting, for example, how much money the government has spent. But the results the CBO reports—like the job creation figures—are simply a function of the inputs it records, not real-world counts.

Following up, the questioner asks for clarification: "If the stimulus bill did not do what it was originally forecast to do, then that would not have been detected by the subsequent analysis, right?" Elmendorf's response? "That's right. That's right."

The stimulus failed based on the Obama Administration's own benchmarks. You know it, I know it, and the American people know it.
