What Are They Singing About?

Health care reform, I know. But what plan? Are they singing about single payer? The Baucus bill? Are they singing about mandated coverage? Or the fine (tax) for not having coverage? It seems like they're just singing about generic improved health care. I won't argue with that. Just so we know what it is. "Just give the President a pen and he'll sketch something out" doesn't work for me.
