Based on his voting history, he could do it, or at least attempt it. Were Obama to say this, most sane people would be checking to make sure it was not April 1

Sen. John McCain (R-Ariz.) plans to promise on Monday that he will balance the federal budget by the end of his first term by curbing wasteful spending and overhauling entitlement programs, including Social Security, his advisers told Politico.

The vow to take on Social Security puts McCain in a political danger zone that thwarted President Bush after he named it the top domestic priority of his second term.

McCain is making the pledge at the beginning of a week when both presidential candidates plan to devote their events to the economy, the top issue in poll after poll as voters struggle to keep their jobs and fill their gas tanks.

As Captain Ed points out

We grew spending by over 35% from 2000, when we had a $2.0 trillion budget.  Some of that went to the war effort, but plenty of it came in other discretionary spending.  And, as McCain tells Politico, the real spending problem isn’t in discretionary programs but in entitlements.  The explosion of spending threatens to overwhelm the federal budget over the next few decades, but already accounts for 58% of federal spending.

In related news, Senator McCain has an in depth plan on what the government can do to help the private sector in creating jobs. Contrast that with the way Obama says he will just create jobs, making us beholden to the federal government.

Furthermore, a very large number of economists are backing McCain’s plans for the economy

We enthusiastically support John McCain’s economic plan. It is a comprehensive, pro-growth, reform agenda. The reform focuses on the real economic problems Americans face today and will face in the future. And it builds on the core economic principles that have made America great.

His plan would control government spending by vetoing every bill with earmarks, implementing a constitutionally valid line-item veto, pausing non-military discretionary government spending programs for one year to stop their explosive growth and place accountability on federal government agencies.

His plan would reduce tax rates by cutting the tax that corporations pay to 25 percent in line with other countries, by completely phasing out the alternative minimum tax, by increasing the exemption for dependents, by permitting the first-year expensing of new equipment and technology, and by making permanent a reformed tax credit for R&D.

His plan would also create a new and much simpler tax system and give Americans a free choice of whether to pay taxes under that simple system or the current complex and burdensome income tax.

His plan would open new markets for American goods and services and thereby create additional jobs for Americans by supporting good free trade agreements, such as the one with Colombia, and working with leaders around the world to avoid isolationism and protectionism. His plan would also reform education, retraining, and other assistance programs so they better help those displaced by trade and other changes in the economy. His plan addresses problems in the financial markets and housing markets by calling for increased transparency and accountability, by targeted assistance to deserving homeowners to refinance their mortgages, and by opposing so-called reform plans which would raise the costs of home-ownership in the future.

The above actions, as well as plans to address entitlement programs — especially Social Security, Medicare and other government health care programs — and his regulatory reforms — especially in the area of health care — constitute a broad and powerful economic agenda. Because of John McCain’s experience working with the American people in all walks of life, with members of Congress on both sides of the aisle, and with leaders around the world, we are optimistic that these plans will become a reality and will create jobs and restore confidence and strong economic growth.
