There's a reason. His re-election depends on the below numbers going into full reverse--and they won't.
It gets worse....
...If the size of the U.S. labor force as a share of the total population was the same as it was when Barack Obama took office—65.7% then vs. 63.8% today—the [top-line] U-3 unemployment rate would be 10.9%.
Oh yeah? What about the Boomer Retirement thing??
Even if you take into account that the LFP should be declining as America ages, the unemployment rate would be 10.5%.
The labor force is growing at ~150,000/month, and 'jobs' is growing at ~75,000/month since Obozo took office. You can toss out the first two years and blame Bush--but that doesn't account for now, does it?
