TRAIN WRECK UPDATE: California takes down online health insurance exchange for small businesses. “The nation’s most populous state has elected to temporarily shutter its new online health insurance marketplace for small business only four months after it launched, dealing yet another blow to a key element of the health care law meant to lower costs for employers. . . . The portals were meant to curb rising health care costs for small businesses by increasing competition among insurers. The White House has said they are intended to allow employers to purchase insurance with the same ease as buying a flight on Web sites like Expedia or Priceline — but in most states, it has not panned out that way yet.”
