Rather than ask potential presidential candidates about their preferred Secret Service code names, Kevin Williamson of National Review Online would like to address meatier subjects.

Here’s my question, which nobody ever really asks: “Given that a small number of federal expenditures — Social Security, Medicare, Medicaid, national security, and interest on the debt — typically constitute about 80 percent of all federal spending, and given that we are not going to cut non-defense discretionary spending to zero, there is no mathematically plausible way to balance the budget without: 1) cutting spending on Social Security, Medicare, Medicaid, and/or national security; and/or 2) raising taxes. So, what’s it going to be: spending cuts in popular programs, higher taxes, or deficits forever? And before you give your answer, I’d like you all to know that standing behind each of you is a man with a Taser and instructions to use it on the first person whose answer relies on the Growth Fairy — lookin’ at you, Jeb — or the Waste, Fraud, and Abuse Fairy. Go.”

I have had the opportunity to put that question privately to a fairly large number of Republican grandees, including some on that debate stage, and I have never received a truly persuasive answer. If any of the 2016 gang would like to provide one, I am sure that National Review would love to see it.

We conservatives, and the Republican elected officials who are, lest we forget, our only real channel of political action, play a game of double make-believe: They’re smart enough to know what the fiscal realities are, but they’re also smart enough to know that campaigning on those realities is a loser, and we understand their dilemma and don’t expect actual policies to look very much like campaign documents, anyway, so everybody ends up pretending that the choice is between competing non-viable budget plans rather than between wishful thinking and reality. My friend Larry Kudlow sometimes wincingly describes the realist school of budget-hawkery as the “eat your spinach” faction or the “root-canal guys,” and no doubt there is real political wisdom informing that view.

But Uncle Stupid desperately needs a root canal, and no amount of wishful thinking or happy talk about self-financing tax cuts is going to change that.
