BOISE, Idaho (AP) — With a looming deadline approaching, insurers are making a last-ditch plea to Gov. C.L. "Butch" Otter for a nonprofit, state-based insurance exchange in Idaho as part of President Barack Obama's health care overhaul. On Tuesday, Idaho's advisers said the state likely has too little time — and too much work still to complete — to establish a state-run exchange by 2014. But insurance companies including Blue Cross of Idaho, Regence Blue Shield and PacificSource urge the state not to default to a federal exchange, like many states are doing. Jack Rovner, an attorney working for the insurers, says Idaho can still develop a state-based nonprofit to manage this online insurance marketplace. Insurers fear a federal exchange would invite regulation from Washington, D.C. Idaho must announce its intentions by Nov. 16.
