The line-item veto expresses liberalism's faith in top-down government and the watery Caesarism that has produced today's inflated presidency. Liberalism assumes that executive branch experts, free from parochial constituencies, know, as Congress does not, what is good for the nation "as a whole." This is contrary to the public philosophy of James Madison's "extensive" republic with its many regions and myriad interests.
If Romney thinks a line-item veto would be a major force for federal frugality, he is mistaken. Gov. Reagan used his line-item veto to trim, on average, only about 2 percent from California's budgets. And much larger proportions of state budgets than of the federal budget are susceptible to such vetoes. Sixty-one percent of the federal budget goes to entitlements and to interest payments on government borrowing, neither of which can be vetoed. Another 21 percent goes to defense and homeland security. Realistically, the line-item veto probably would be pertinent to less than 20 percent of the budget.
And the line-item veto might result in increased spending. Legislators would have even less conscience about packing the budget with pork, because they could get credit for putting in what presidents would be responsible for taking out. Presidents, however, might use the pork for bargaining, saying to individual legislators: If you support me on this and that, I will not veto the bike path you named for your Aunt Emma.
After a century of the growth of presidential power, and after eight years of especially aggressive assertions of presidential prerogatives, it would be unseemly to intensify this tendency with a line-item veto. Conservatives used to be the designated worriers about the evolution of the presidency into the engine of grandiose government. They should visit the Rotunda for the Charters of Freedom in the National Archives building on Constitution Avenue. There the Constitution is displayed under four large glass plates. Almost half of the glass is required to cover just Article One. That concerns the legislative branch, which is the government's "first branch" for a reason.
A polite assessment of Romney's -- and Giuliani's -- enthusiasm for a line- item veto would resemble a 19th-century scholar's assessment of a rival's translation of Plato: "The best translation of a Greek philosopher which has ever been executed by a person who understood neither philosophy nor Greek."
