The most telling moment of the debate might have been Romney's inability to answer a basic question about his plans for military spending.
He surely must have known that such a question was likely. There have been a number of recent articles about his promise to spend at least 4 percent of GDP on the Pentagon's base budget, first articulated in a defense and foreign-policy white paper and reiterated on his website. Moderator Bob Schieffer asked, not unreasonably, "Governor... Where are you going to get the money?"
Romney replied that "we're going to cut about 5 percent from the discretionary budget, excluding military," and he invited Schieffer to "come on our website" to see "how we get to a balanced budget within 8 to 10 years."
But Romney's numbers don't add up. According to the CBO's latest projections (Table 1-3), nondefense discretionary spending over the next decade (2013–2022) will total $5.494 trillion. Five percent of that equals $274.7 billion. Sequestration would eliminate another $356 billion, assuming that he could push those cuts through Congress while protecting the Pentagon. According to my most conservative estimate, Romney's 4 percent goal, assuming that he won't actually reach it until the end of a second term, will generate $1.7 trillion in additional spending. Cutting domestic discretionary spending, therefore, doesn't come close to covering the costs of Romney's plans. So, I ask, "Governor, where are you going to get the money?"
But perhaps we were witnessing another Etch A Sketch moment? Romney said last night that he would not cut military spending, but he did not reiterate his 4 percent goal. Could it be that Romney is moving away from it?
One can only hope. It was never smart to peg military spending to GDP, and it was doubly foolish to pick an arbitrary number so completely oblivious to fiscal reality.
