It's obviously going to be hard to achieve the unacknowledged goal of many mainstream journalists -- the president's re-election -- if the economic slump continues. So they characterize economic setbacks as unexpected, with the implication that there's still every reason to believe that, in Herbert Hoover's phrase, prosperity is just around the corner.
A less cynical explanation is that many journalists really believe that the Obama administration's policies are likely to improve the economy. Certainly that has been the expectation as well as the hope of administration policymakers.
Obama's first Council of Economics Adviser Chairman Christina Romer, whose scholarly work is widely respected, famously predicted that the February 2009 stimulus package would hold unemployment below 8 percent. She undoubtedly believed that at the time; she is too smart to have made a prediction whose failure to come true would prove politically embarrassing.
But unemployment zoomed to 10 percent instead and is still at 9 percent. Political pundits sympathetic to the administration have been speculating whether the president can win re-election if it stays above the 8 percent mark it was never supposed to reach.
Administration economists are now making the point that it takes longer to recover from a recession caused by a financial crisis than from a recession that occurs in the more or less ordinary operation of the business cycle. There's some basis in history for this claim.
But it come a little late in the game. Obama and his policymakers told the country that we would recover from the deep recession by vastly increasing government spending and borrowing. We did that with the stimulus package, with the budget passed in 2009 back when congressional Democrats actually voted on budgets, and with the vast increases scheduled to come (despite the administration's gaming of the Congressional Budget Office scoring process) from Obamacare.
All of this has inspired something like a hiring strike among entrepreneurs and small businessmen. Employers aren't creating any more new jobs than they were during the darkest days of the recession; unemployment has dropped slowly because they just aren't laying off as many employees as they did then.
In the meantime many potential job seekers have left the labor market. If they re-enter and look for jobs, the unemployment rate will stay steady or ebb only slowly.
We tend to hire presidents who we think can foresee the future effect of their policies. No one does so perfectly. But if the best sympathetic observers can say about the results is that they are "unexpected," voters may decide someone else can do better.
