CONCORD, N.H. (AP) — Consumer and small business advocates in New Hampshire are disappointed but not surprised that only one company plans to sell insurance through the new online marketplaces required under President Barack Obama's health care overhaul. Companies have until June 1 to submit applications to the state, but an official with Anthem Blue Cross/Blue Shield of New Hampshire said last week that it is the only insurer that has applied to sell either individual or small group plans through the new markets. The insurance department confirmed that is the case.
