I discuss the Limited Government Amendment in more detail in a longer piece over at National Affairs. But here it is, in a nutshell:

The amendment would limit the annual increase in federal spending to 2 percent (above inflation). It would grant an exception allowing for unlimited defense spending during a time of congressionally declared war. And it would allow three-quarters of the states (acting upon the request of two-thirds of Congress) to issue a 1-year exception for any reason whatsoever. In these ways, the amendment would constrain Congress, while leaving us with the flexibility to deal with what Hamilton called the full “extent and variety of national exigencies,” which no nation can foresee but which every nation must be prepared to address.

Would such an amendment really make that much of a difference? It would make a colossal difference.
