What was that about turning a corner again? Twenty-two states reported a drop in payroll jobs last month, double the number for June, according to new Labor Department statistics.

The battleground states showing job losses in July were Florida, Michigan, Minnesota, Missouri, Pennsylvania and New Mexico, according to Labor Department figures released Aug. 20.
