Remember those "other" new Obamacare exchanges—the ones that small businesses were supposed to use to sign up workers for health insurance?
Yeah, well, apparently a whole bunch of small businesses forgot about them, too.
A new Government Accountability Office report finds that a stunningly low number of workers have enrolled in insurance plans sold on small-business health exchanges run by federal and state governments.

The report suggests that the Small Business Health Options Program exchanges will fall well short of the 2 million people that had been projected to sign up by January.
As of last summer, only about 76,000 people working for about 12,000 employers had enrolled in insurance plans sold by 18 state-run SHOP exchanges, according to the GAO report released Thursday.
While the other 33 SHOP exchanges run by the federal government didn't have enrollment data available for the GAO, officials in charge of them "do not expect major differences in enrollment trends between" the state-run SHOP exchanges and their federally run counterparts, the report noted. The federal Centers for Medicare and Medicaid Service was still compiling enrollment data from insurers and did not expect complete numbers until early 2015, the GAO said.
