It's impossible to overstate how incredible this is:
- The Senate is planning to vote today to begin debate on a health care bill.
- No one knows which one — which means no one knows what it would do. Would it fundamentally restructure Medicaid? Would it send individual insurance markets across the country into a tailspin?
- The Senate won't know until it has already voted, later in the week, on one bill or another. And all of the available options still have major holes.
But their chances of getting there seem to be improving.
