Falling jobless rate is good news for Obama- but the trend is fragile

The Washington Post reports:

The unemployment rate dipped to its lowest level in nearly three years last month, good news that on Friday rippled through rival presidential campaigns whose prospects could hinge on the pace of the economic recovery.

Unemployment has declined in four consecutive months, to 8.5 percent, its lowest level since the president’s second month in office. However fragile, it is the kind of trend that President Obama is counting on to convince voters that he deserves a second term in the White House.
