I'd very much support this as long as it doesn't lead to a single payer system for the rest of us.  It is pretty clear that people with certain health problems cannot be covered under the current system.  Trying to cover them under the current system leads to issues with the entire system.  There are just two problems that need to be dealt with.  First, insurance companies may declare everything a "pre-existing condition" and dump all sick people onto Medicare.  There needs to be a definition of what is a "pre-existing condition" as well as a prohibition to denying others insurance.  Second, people who choose not to by insurance should have to pay a penalty for "free-riding" if they need the Medicare option.  This should only be for people with over a certain income level.
