Yeah, that's right. The Obama "stimulus" bill, after over two years since enactment, is only 82.73 % spent.
Screen-cap from Recovery.gov:
259.9 + 207.3 + 183.9 = $651.1 billion
651.1 / 787 = 82.73%
Recall that the entire point of a Keynesian stimulus is to spend it, and to spend it quickly. Obama couldn't even get that much right.
