Something stinks.

WASHINGTON (AP) – The U.S. unemployment rate fell to 7.8 percent last month, dropping below 8 percent for the first time in nearly four years. The rate declined because more people found work, a trend that could have an impact on undecided voters in the final month before the presidential election.

The Labor Department said Friday that employers added 114,000 jobs in September. The economy also created 86,000 more jobs in July and August than first estimated. Wages rose in September and more people started looking for work.

The revisions show employers added 146,000 jobs per month from July through September, up from 67,000 in the previous three months. The unemployment rate fell from 8.1 percent in August, matching its level in January 2009 when President Barack Obama took office.

The decline could help Obama, who is coming off a disappointing debate performance against GOP challenger Mitt Romney.

Update: Santelli smells a rat.

Update II: One of the main reasons the rate fell was because of a surge in part-time jobs.

Via AEI:

Only in an era of depressingly diminished expectations could the September jobs report be called a good one. It really isn’t. Not at all.

1. Yes, the U-3 unemployment rate fell to 7.8%, the first time it has been below 8% since January 2009. But that’s only due to a flood of 582,000 part-time jobs. As the Labor Department noted:

“The number of persons employed part time for economic reasons (sometimes referred to as involuntary part-time workers) rose from 8.0 million in August to 8.6 million in September. These individuals were working part time because their hours had been cut back or because they were unable to find a full-time job.”

2. The broader U-6 rate — which takes into account part-time workers who want full-time work and lots of discouraged workers who’ve given up looking — stayed unchanged at 14.7%. That’s a better gauge of the true unemployment rate and state of the American labor market.
