The Colorado Health Foundation sponsors the annual Colorado Health Symposium, one of the premier health care conferences in the country. The 30th edition was last month in Keystone, and one of the highlights was a debate on whether the Affordable Care Act should be repealed. It will be aired on Rocky Mountain PBS on Thursday at 9 p.m. (Channel 6 in Denver, Channel 8 in Colorado Springs-Pueblo, Channel 18 in Grand Junction and Channel 20 in Durango.)
