Elected leaders in Portland, OR, have unanimously pledged to become one of the first cities in the country to offer health insurance. The City Council voted 5-0 for a resolution that convenes a working group to figure out how to provide coverage for preschoolers and children in public schools—Portland has an estimated 12,000 children without health insurance. But because backers haven't begun to work out the details, it's unclear how much the city would have to spend on the insurance or how it would pay for the plan.
