The one state that not only embraced Obamacare but insisted on going beyond it to a full single-payer system was Vermont, the haven of hippies and expatriate New Yorkers, which has become one of the most liberal states in the nation. In 2011, it adopted a form of neighboring Canada’s government-financed health care and promised to implement it by 2017. (And Jonathan Gruber was a key architect of this plan as well as of Obamacare.) This week, however, Governor Peter Shumlin, a Democrat, admitted the state couldn’t afford the plan’s $2 billion price tag and consequent sky-high taxes, and pulled the plug. The lessons for Obamacare are obvious and profound.

Avik Roy: Last week, Vermont Governor Peter Shumlin (D.) announced that he was pulling the plug on his four-year quest to impose single-payer, government-run health care on the residents of his state. “In my judgment,” said Shumlin at a press conference, “the potential economic disruption and risks would be too great to small businesses, working families, and the state’s economy.” The key reasons for Shumlin’s reversal are important to understand. They explain why the dream of single-payer health care in the U.S. is dead for the foreseeable future—but also why Obamacare will be difficult to repeal.
