We know how everyone in Washington feels about the health-care reform bill's public option, but now we know where the public stands. According to a new NBC News poll (that surveyed 805 adults) out Tuesday, 47 percent of Americans oppose the public plan, while 43 percent support it. This is a shift from a poll conducted last month, in which 46 percent said they supported it, and only 44 percent were opposed. When asked in the new poll what they thought the public option would do, 45 percent said they thought it would lower health-care costs and provide coverage for the uninsured. Forty-eight percent, on the other hand, felt the option would reduce the choice of doctors and limit access to treatment.
