We’ll spend the hour with Dr. Paul Song, a radiation oncologist, Executive Chairman of Courage Campaign, and Board member of Physicians for a National Health Program, about the Health insurance exchange roll-out starting on Tuesday – it’s the most significant milestone of Obamacare. Dr. Song will explain everything you need to know about California’s online exchange – how you can shop for coverage, whether you’re eligible for subsidies, and the politics of Obamacare. And we’ll take your questions and comments.
