The U.S. unemployment rate took a big tumble in November, from 9 percent to 8.6 percent, according to the government's monthly jobs data. Still, it's probably too soon to pop the champagne corks. A combination of forces caused the big drop, some good and some bad.
Getting a big fall in the unemployment rate is always good news in the White House, but President Obama was careful not to gloat at an appearance Friday in Washington.
"This morning we learned that our economy added another 140,000 private sector jobs in November. The unemployment rate went down," he said.
