as someone from VT, VT was way too small to do single-payer on it's own The whole point of single payer is to have a monopsony that can effectively negotiate with everyone else. For it to have a chance, they would have had to join with MA.
I think the reform that would be acceptable to the median voter is a public option for Obamacare. Just let people select Medicare as an option instead of one of the private companies (and even better, let companies provide it as an option for their employees as well).
