Following up on Craig's post earlier this evening, I wanted to point out some of the really good points that Spencer Ackerman over at the Washington Independent and Matt Yglesias over at Think Progress have been making all day about President Obama's recently announced spending freeze. Ackerman asks why in the world defense spending should go unaffected and Yglesias adds that, while there are reasons to treat various kinds of spending and taxes differently, "the security / non-security distinction doesn’t hold up ... at all."
