It was a day of prognostications as America's Health Insurance Plans turned the stage over to former lawmakers and presidential advisers to discuss the future of U.S. healthcare during the group's annual meeting in San Francisco, writes Wall Street Journal blogger Kristen Gerencher. Among the speakers were three people hands-on experience in healthcare policy, including former Sen. John Breaux, former Senate Majority Leader Bill Frist and Former Secretary of Health and Human Services Tommy Thompson. Gerencher also notes that protesters surrounded the conference building behind police barricades erected to allow attendees a space to come and go.
