A Balanced Budget Amendment

Bruce Bartlett tees off on a balanced budget Constitutional amendment sponsered by all 47 Republican senators:

I won't repeat all of my previous criticisms of the balanced budget amendment that can be found in the links. But let me discuss one other thing. The gross domestic product is not a concept defined in law and is revised constantly; from time to time, the Bureau of Economic Analysis revises the GDP data all the way back to 1929. And of course, the 18 percent figure is totally arbitrary; the proposal effectively assumes that all federal outlays consist of funds that are appropriated annually, rather than consisting primarily of mandatory programs such as Social Security, Medicare and interest on the debt. Even if Congress was willing to cut mandatory spending, it is practically impossible to do so quickly unless it is willing to reduce the monthly checks going to current retirees and other actions difficult to contemplate.
In short, this is quite possibly the stupidest constitutional amendment I think I have ever seen. It looks like it was drafted by a couple of interns on the back of a napkin. Every senator cosponsoring this POS should be ashamed of themselves. (emphasis mine)

That is coming from one of Ronald Reagan's policy analysts.  That is amazing.
