The list is actually longer than that- add the Minnesota Nurses Asscociation and the New York State Nurses Association. There are others as well.
The UAN is also supporting national staffing ratio legislation- H.R. 2123
Three of the four states that left the UAN in December went for the hospital industry sponsored type of legislation (Ohio, Oregon, and Washington). Washington's was just signed into law.

Having these industry sponsored bills get passed makes the really progressive work even more challenging.
