The White House came out in support of Iowa Rep. Jim Nussle's proposed bill that places limits on discretionary spending. Through the No Child Left Behind Act, nation building in Iraq, free prescription drugs for seniors, and various other scemes to boost federal spending--for AIDS, the NEA, a trip to Mars--President Bush's four budgets enlarged government by about 30 percent. It would have been nice if he had embraced the spirit of Rep. Nussle's bill three-and-a-half years ago.
