On paper it looked like an economics dream team: Larry Summers, Christina Romer, and Austan Goolsbee, not to mention Peter Orszag, Tim Geithner, and Paul Volcker. The inside story, however, is that the president was wholly unable to manage the mighty brains—and egos—he had assembled to advise him.

According to Ron Suskind’s book Confidence Men, Summers told Orszag over dinner in May 2009: “You know, Peter, we’re really home alone … I mean it. We’re home alone. There’s no adult in charge. Clinton would never have made these mistakes [of indecisiveness on key economic issues].” On issue after issue, according to Suskind, Summers overruled the president. “You can’t just march in and make that argument and then have him make a decision,” Summers told Orszag, “because he doesn’t know what he’s deciding.” (I have heard similar things said off the record by key participants in the president’s interminable “seminar” on Afghanistan policy.)

This problem extended beyond the White House. After the imperial presidency of the Bush era, there was something more like parliamentary government in the first two years of Obama’s administration. The president proposed; Congress disposed. It was Nancy Pelosi and her cohorts who wrote the stimulus bill and made sure it was stuffed full of political pork. And it was the Democrats in Congress—led by Christopher Dodd and Barney Frank—who devised the 2,319-page Wall Street Reform and Consumer Protection Act (Dodd-Frank, for short), a near-perfect example of excessive complexity in regulation. The act requires that regulators create 243 rules, conduct 67 studies, and issue 22 periodic reports. It eliminates one regulator and creates two new ones.

It is five years since the financial crisis began, but the central problems—excessive financial concentration and excessive financial leverage—have not been addressed.

Today a mere 10 too-big-to-fail financial institutions are responsible for three quarters of total financial assets under management in the United States. Yet the country’s largest banks are at least $50 billion short of meeting new capital requirements under the new “Basel III” accords governing bank capital adequacy.

And then there was health care. No one seriously doubts that the U.S. system needed to be reformed. But the Patient Protection and Affordable Care Act (ACA) of 2010 did nothing to address the core defects of the system: the long-run explosion of Medicare costs as the baby boomers retire, the “fee for service” model that drives health-care inflation, the link from employment to insurance that explains why so many Americans lack coverage, and the excessive costs of the liability insurance that our doctors need to protect them from our lawyers. …

A much more accurate term would be “Pelosicare,” since it was she who really forced the bill through Congress.

Pelosicare was not only a political disaster. Polls consistently showed that only a minority of the public liked the ACA, and it was the main reason why Republicans regained control of the House in 2010. It was also another fiscal snafu. The president pledged that health-care reform would not add a cent to the deficit. But the CBO and the Joint Committee on Taxation now estimate that the insurance-coverage provisions of the ACA will have a net cost of close to $1.2 trillion over the 2012–22 period.

The president just kept ducking the fiscal issue. Having set up a bipartisan National Commission on Fiscal Responsibility and Reform, headed by retired Wyoming Republican senator Alan Simpson and former Clinton chief of staff Erskine Bowles, Obama effectively sidelined its recommendations of approximately $3 trillion in cuts and $1 trillion in added revenues over the coming decade. As a result there was no “grand bargain” with the House Republicans—which means that, barring some miracle, the country will hit a fiscal cliff on Jan. 1 as the Bush tax cuts expire and the first of $1.2 trillion of automatic, across-the-board spending cuts are imposed. The CBO estimates the net effect could be a 4 percent reduction in output.

The failures of leadership on economic and fiscal policy over the past four years have had geopolitical consequences. The World Bank expects the U.S. to grow by just 2 percent in 2012. China will grow four times faster than that; India three times faster. By 2017, the International Monetary Fund predicts, the GDP of China will overtake that of the United States. …

America under this president is a superpower in retreat, if not retirement. Small wonder 46 percent of Americans—and 63 percent of Chinese—believe that China already has replaced the U.S. as the world’s leading superpower or eventually will.

It is a sign of just how completely Barack Obama has “lost his narrative” since getting elected that the best case he has yet made for reelection is that Mitt Romney should not be president. In his notorious “you didn’t build that” speech, Obama listed what he considers the greatest achievements of big government: the Internet, the GI Bill, the Golden Gate Bridge, the Hoover Dam, the Apollo moon landing, and even (bizarrely) the creation of the middle class. Sadly, he couldn’t mention anything comparable that his administration has achieved.

Now Obama is going head-to-head with his nemesis: a politician who believes more in content than in form, more in reform than in rhetoric. In the past days much has been written about Wisconsin Congressman Paul Ryan, Mitt Romney’s choice of running mate. I know, like, and admire Paul Ryan. For me, the point about him is simple. He is one of only a handful of politicians in Washington who is truly sincere about addressing this country’s fiscal crisis. …

Mitt Romney is not the best candidate for the presidency I can imagine. But he was clearly the best of the Republican contenders for the nomination. He brings to the presidency precisely the kind of experience—both in the business world and in executive office—that Barack Obama manifestly lacked four years ago. (If only Obama had worked at Bain Capital for a few years, instead of as a community organizer in Chicago, he might understand exactly why the private sector is not “doing fine” right now.) And by picking Ryan as his running mate, Romney has given the first real sign that—unlike Obama—he is a courageous leader who will not duck the challenges America faces.

The voters now face a stark choice. They can let Barack Obama’s rambling, solipsistic narrative continue until they find themselves living in some American version of Europe, with low growth, high unemployment, even higher debt—and real geopolitical decline.
