When I put the same question to economists, they shrugged. Maybe it was because an additional 582,000 Americans were working part time, which doesn’t show up in payroll statistics. Maybe it was because of increased government employment. For some unexplained reason, there is always an uptick in September. (“Maybe it has something to do with going back to school,” said Mark Zandi of Moody’s Analytics, who quickly added, “I’m just guessing here.”) In any case, it wasn’t anything economists hadn’t seen before. Sometimes the two surveys delink, though over the long term they tend to reinforce each other. In the short term, however, the household survey is considered the more volatile — and less reliable — of the two numbers.

Which leads to Point No. 3: there is something truly absurd about having the presidential race hinge on the unemployment rate. Even putting aside the reliability of the short-term numbers, the harsh reality is that no president has much control over the economy. That is especially true of President Obama, whose every effort to boost the economy these past two years has been stymied by Republicans. Again and again, they have shown that they would rather see the country suffer than do anything that might help Obama’s re-election.

There is rough justice in the way things are playing out. Having spent the last year wrongly blaming the president for high unemployment, Republicans can only stand by helplessly as the unemployment rate goes down at the worst possible moment for them. Fox News scoured the data Friday, looking for signs that the economy wasn’t improving. They found some: high unemployment for African-Americans, for instance, and fewer manufacturing jobs.

But the data were largely overwhelmed by positive signals. In its revised figures for July and August, for instance, the bureau said that more jobs had been created than it originally estimated. People with only high school degrees were finding jobs. The number of people who had been out of work for six months or more was at its lowest point in three years.

Whether the Republicans like it or not, the economy is slowly getting better.

Awful, isn’t it?
