Senator John McCain and other budget reformers are right to rail against the institutionized corruption of federal “earmarking.” Earmarks are, however, just a small part of the massive bloat in the federal budget. Earmark reform is needed, but presidential candidate McCain needs to propose more fundamental budget reforms in the coming months.

Representatives John Campbell (R-CA) and Jeb Hensarling (R-TX) have just introduced an idea that McCain could champion: A constitutional cap on the overall federal budget. You can read the proposed amendment here, but essentially these House budget experts propose that annual federal spending growth should not exceed the long-run average growth in the U.S. economy, except with a two-thirds vote or a declared war.

I’ve proposed a similar budget cap that would be statutory, not constitutional, and thus easier to implement. See here and here.

Either way, the point for Mr. McCain (or Mr. Obama, if he is so inclined) is to promote some sort of overall cap on the budget to drive home that the government’s budget should not grow any faster than the average family’s budget.
