Oregon doesn’t have single payer per se, but everyone who wants health insurance can get it: there is a state-mandated risk pool, which offers standard health insurance at no more than 125% of the state average rate, regardless of personal medical history. In fact, in order to get into this program, you have to have been turned down for medical insurance.
Oregon is pretty liberal, and I, personally, really like the weather. It doesn’t rain as much as everyone thinks, and it’s rarely below freezing in the winter–the weather then is a lot nicer than many places further south. And of course, the summer is glorious.
In general, Oregon’s tax and public services structure is geared toward the “little guy” (and to some extent, screwing the “big guy,” which is why we have a hostile business climate and high unemployment).
