Because each state has different laws and then the crying that "they" are trampling all over states' rights would commence if they were to allow private insurers to go across state lines. From my view point either way the conservatives would whine about either direction taken.
While I do appreciate the fact that you don't miss a chance to piss on conservatives I only wish that you had answered the question. You did however, answer "a" question, just not "either" of the questions I asked.
However, in response to your tangential answer let me then ask this. Based upon your argument of States rights superceding Federal trampling shouldn't then, States have the right to not impose Medicare upon its citizens, or do we then get into the Commerce Clause fiasco.
Or you can have another chance of answering either one of the original questions, 1. How can Medicare, being free to cross state lines free of costly state mandated add on insurance protections still be scheduled to be bancrupt within the next ten years, or 2. and this could be a fun one for you, am I missing something here as to why and how Medicare can be bancrupt while private insurers are raking in the dough?
