Other states the will follow Mass?

I saw on the news that Mass. wants to pass a bill or whatever so that everyone has health coverage in the state. I believe they say that it is more than likely that it will pass. If it does pass in Mass. what other states do you think will likely follow? I definately see the New England states following Mass. I see Minnesota doing it as well. I would love to see Illinois do it, but most likely that would never happen.>
