Dave Koenig has health insurance through work, and is happy with the plan. But as the health care debate drags on, he says he's losing faith in the overhaul plan. Koenig, who calls himself a conservative, says that at first he was open to President Obama's call to regulate the insurance industry to protect patients. But as lawmakers negotiate behind closed doors, and it's still unclear how much it will cost, Koenig is growing wary of the plan. And he's hoping his health insurance won't change when all is said and done.
