Voting analysis

One of Lori Trahan's bills would establish in statute a definition of an essential health system. Defining a category is not a glamorous legislative act, but it is often the whole fight — once a class of hospital is named in law, funding formulas and protections can attach to it, and until then every argument starts from scratch.
